Grove High Temperature Sensor

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).

Platforms Supported

Getting Started

Play with Arduino

Hardware

• Step 1. We need to prepare the below stuffs:

Seeeduino V4.2	Base Shield	Grove-High Temperature Sensor
Get ONE Now	Get ONE Now	Get ONE Now

• 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

Software

• 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.

Play With Raspberry Pi

Hardware

• Step 1. Prepare the below stuffs:

Raspberry pi	GrovePi_Plus	Grove - Ultrasonic Ranger
Get ONE Now	Get ONE Now	Get ONE Now

• 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.

Software

• 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
