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).

!!!Tip More details about Grove modules please refer to Grove System
Step 1. We need to prepare the below stuffs:
Seeeduino V4.2
Base Shield
Grove-High Temperature Sensor
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.
!!!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
Step 1. Download the UltrasonicRanger Library from Github.
Step 2. Refer How to install library to install library for Arduino.
Step 3. Copy the code into Arduino IDE and upload.
#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.
Step 1. Prepare the below stuffs:
Raspberry pi
GrovePi_Plus
Grove - Ultrasonic Ranger
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.
Step 1. Follow 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.
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
