# Grove High Temperature Sensor ![](https://raw.githubusercontent.com/SeeedDocument/Grove-High_Temperature_Sensor/master/img/High_Temperature_Sensor_01.jpg) Thermocouples are very sensitive devices. It requires a good amplifier with cold-junction compensation. The Grove - High Temperatire Sensor uses a K-Type themocouple and a thermocouple amplifier that measures ambient temperature using thermistor for cold-junction compensation. The detectable range of this Sensor is -50\~600°C , and the accuracy is ±(2.0% + 2°C).

We need to prepare the below stuffs: | Seeeduino V4.2 | Base Shield | Grove-High Temperature Sensor | | -------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------- | | ![enter image description here](https://raw.githubusercontent.com/SeeedDocument/Grove_Light_Sensor/master/images/gs_1.jpg) | ![enter image description here](https://raw.githubusercontent.com/SeeedDocument/Grove_Light_Sensor/master/images/gs_4.jpg) | ![enter image description here](https://github.com/SeeedDocument/Grove-High_Temperature_Sensor/raw/master/img/High_Temperature_Sensor_s.jpg) | | [Get ONE Now](http://www.seeedstudio.com/Seeeduino-V4.2-p-2517.html) | [Get ONE Now](https://www.seeedstudio.com/Base-Shield-V2-p-1378.html) | [Get ONE Now](https://seeedstudio.com/Grove-High-Temperature-Sensor-p-1810.html) | * Step 2. Connect the Grove-High Temperature Sensor to **A0** on Base Shield. * Step 3. Plug the base Shield into Seeeduino-V4.2. * Step 4. Connect Seeeduino-V4.2 to PC by using a USB cable. ![](https://github.com/SeeedDocument/Grove-High_Temperature_Sensor/raw/master/img/arduino_connection.jpg) !!!Note If we don't have a Base Shield, don't worry, the sensor can be connected to your Arduino directly. Please follow below tables to connect with Arduino. | Seeeduino | Grove-High Temperature Sensor | | --------- | ----------------------------- | | GND | Black | | 5V | Red | | A1 | White | | A0 | Yellow | #### Software * Step 1. Download the [ UltrasonicRanger Library](https://github.com/Seeed-Studio/Grove_HighTemp_Sensor/archive/master.zip) from Github. * Step 2. Refer [How to install library](http://wiki.seeed.cc/How_to_install_Arduino_Library) to install library for Arduino. * Step 3. Copy the code into Arduino IDE and upload. ```cpp #include "High_Temp.h" HighTemp ht(A1, A0); void setup() { Serial.begin(115200); Serial.println("grove - hight temperature sensor test demo"); ht.begin(); } void loop() { Serial.println(ht.getThmc()); delay(100); } ``` * Step 4. Open your Serial Monitor and set baud rate as 115200, We will see the temperature in Celsius here. ![](https://raw.githubusercontent.com/SeeedDocument/Grove-High_Temperature_Sensor/master/img/Htsdata.jpg) ### Play With Raspberry Pi #### Hardware * Step 1. Prepare the below stuffs: | Raspberry pi | GrovePi\_Plus | Grove - Ultrasonic Ranger | | ----------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------- | | ![enter image description here](https://github.com/SeeedDocument/Grove_Ultrasonic_Ranger/raw/master/img/rasp.jpg) | ![enter image description here](https://github.com/SeeedDocument/Grove_Ultrasonic_Ranger/raw/master/img/Grovepi%2B.jpg) | ![enter image description here](https://github.com/SeeedDocument/Grove-High_Temperature_Sensor/raw/master/img/High_Temperature_Sensor_s.jpg) | | [Get ONE Now](https://www.seeedstudio.com/Raspberry-Pi-3-Model-B-p-2625.html) | [Get ONE Now](https://www.seeedstudio.com/GrovePi%2B-p-2241.html) | [Get ONE Now](https://seeedstudio.com/Grove-High-Temperature-Sensor-p-1810.html) | * Step 2. Plug the GrovePi\_Plus into Raspberry. * Step 3. Connect Grove-Ultrasonic ranger to **A0** port of GrovePi\_Plus. * Step 4. Connect the Raspberry to PC through USB cable. ![](https://github.com/SeeedDocument/Grove-High_Temperature_Sensor/raw/master/img/raspberry_connection.jpg) #### Software * Step 1. Follow [Setting Software](https://www.dexterindustries.com/GrovePi/get-started-with-the-grovepi/setting-software/) to configure the development environment. * Step 2. Git clone the Github repository. ``` cd ~ git clone https://github.com/DexterInd/GrovePi.git ``` * Step 3. Excute below commands to use the ultrasonic\_ranger to meansure the distance. ``` cd ~/GrovePi/Software/Python/grove_hightemperature_sensor python high_temperature_example.py ``` Here is the grove\_ultrasonic.py code. ```python import grove_hightemperature_sensor as grovepi # our library from time import sleep # and for the sleep function import sys # we need this for the exception throwing stuff # Don't forget to run it with Python 3 !! # Don't forget to run it with Python 3 !! # Don't forget to run it with Python 3 !! def Main(): room_temperature_pin = 15 # this is equal to A1 probe_temperature_pin = 14 # this is equal to A0 # so you have to connect the sensor to A0 port # instatiate a HighTemperatureSensor object sensor = grovepi.HighTemperatureSensor(room_temperature_pin, probe_temperature_pin) # and do this indefinitely while True: # read the room temperature room_temperature = sensor.getRoomTemperature() # and also what's important to us: the temperature at the tip of the K-Type sensor probe_temperature = sensor.getProbeTemperature() # print it in a fashionable way print('[room temperature: {:5.2f}°C][probe temperature: {:5.2f}°C]'.format(room_temperature, probe_temperature)) # and wait for 250 ms before taking another measurement - so we don't overflow the terminal sleep(0.25) if __name__ == "__main__": try: Main() # in case CTRL-C / CTRL-D keys are pressed (or anything else that might interrupt) except KeyboardInterrupt: print('[Keyboard interrupted]') sys.exit(0) # in case there's an IO error aka I2C except IOError: print('[IO Error]') sys.exit(0) # in case we have a math error (like division by 0 - can happen depending on the read values) # or if the values exceed a certain threshold # experiment and you'll see except ValueError as e: print('[{}]'.format(str(e))) sys.exit(0) ``` * Step 4. We will see the temperature display on terminal as below. ``` pi@raspberrypi:~/GrovePi/Software/Python/grove_hightemperature_sensor $ python high_temperature_example.py [room temperature: 20.47°C][probe temperature: 32.19°C] [room temperature: 20.47°C][probe temperature: 32.19°C] [room temperature: 20.47°C][probe temperature: 32.19°C] [room temperature: 20.47°C][probe temperature: 32.19°C] [room temperature: 20.60°C][probe temperature: 32.19°C] [room temperature: 20.60°C][probe temperature: 32.19°C] [room temperature: 20.60°C][probe temperature: 32.19°C] ``` ## FAQ Please click [here](http://support.seeedstudio.com/knowledgebase/articles/743697-grove-high-temperature-sensor-sku-111020002) to see all Grove-High\_Temperature\_Sensor FAQs. ## Tech Support Please do not hesitate to contact **** if you require further information. ## Resources * **\[PDF]** [Download Wiki PDF](https://github.com/SeeedDocument/Grove_Ultrasonic_Ranger/raw/master/res/Grove-High_Temperature_Sensor.pdf) * **\[PDF]**[Grove - High Temperature Sensor SCH PDF](https://raw.githubusercontent.com/SeeedDocument/Grove-High_Temperature_Sensor/master/res/Grove-High_Temperature_Sensor_v1.0.pdf) * **\[PDF]**[Grove - High Temperature Sensor PCB PDF](https://github.com/SeeedDocument/Grove-High_Temperature_Sensor/raw/master/res/Grove%20-%20High%20Temperature%20Sensor%20v1.0%20-%20PCB.pdf) * **\[Eagle]**[Grove - High Temperature Sensor Eagle SCH](https://github.com/SeeedDocument/Grove-High_Temperature_Sensor/raw/master/res/Grove%20-%20High%20Temperature%20Sensor%20v1.0.sch.zip) * **\[Eagle]**[Grove - High Temperature Sensor Eagle PCB](https://github.com/SeeedDocument/Grove-High_Temperature_Sensor/raw/master/res/Grove%20-%20High%20Temperature%20Sensor%20v1.0%20.brd.zip) * **\[Library]**[High Temperature Sensor Library](https://github.com/Seeed-Studio/Grove_HighTemp_Sensor) * **\[Datasheet]**[OPA333 PDF](http://www.ti.com/lit/ds/symlink/opa333.pdf) * **\[Datasheet]**[LMV358 PDF](https://raw.githubusercontent.com/SeeedDocument/Grove-High_Temperature_Sensor/master/res/Lmv358.pdf)
