Raspberry Pi Dual Thermocouple Plate
Description:
This is a board(plate in Raspberry Pi language) that allows reading the temperature through two thermocouple sensors.
WARNING ! ESD( electrostatic-sensitive device) .
Temperature Range:
Maximum temperature allowed range is : 0 to +819 degrees Celsius (1500 degrees Fahrenheit)
Maximum temperature using the present sensor is +350 degrees Celsius (662 degrees Fahrenheit)
Connecting the temperature sensor (thermocouple )
Connect the sensor + terminal to the board + terminal (the connector on the board that has a big K on it )
Compatibility :
Models A,B, B+ ,2,2+,3
Setting up the environment:
These instructions are for Raspbian. Because it uses the I2C Protocol , we need to enable it .
Setting the I2c Interface:
Type
sudo raspi-config
1.A menu will show (Raspberry Pi Software Configuration Tool)
2.Go to Advanced options (8)
3.Go to I2C
4. Would you like the ARM I2c interface to be enabled ? YES
5. The ARM I2C interface is enabled. OK
6.Would you like the I2C Kernel module to be loaded by default YES
7From the main Menu press finish
Installation:
1.First install those packages(they allow access to I2Cc bus) :
sudo apt-get install python-smbus
sudo apt-get install i2c-tools
2.Please download robogaia_dual_thermocouple_scripts.tar.gz (it is on the bottom of the page)
3.Unzip the file:
sudo tar xzvf robogaia_dual_thermocouple_scripts.tar.gz
4. Go to the uncompressed folder
cd robogaia_dual_thermocouple
The example scripts are inside.
Usage:
sudo ./dual_read_remperature_celsius // will read the temperatures in Celsius
sudo ./dual_read_remperature_fahrenheit // will read the temperatures in Fahrenheit
