» SW 06: Temperature Sensor

Turn on the Smart Water Board and reads the Temperature sensor printing the result through the USB

Required Materials

1 x Waspmote
1 x Battery
1 x Smart Water Sensor Board
1 x PT1000 temperature Sensor

Notes

PT1000 sensor is generally used with the pH sensor for temperature compensation
It is advisable to space at least ten seconds the measurements of the PT1000 sensor in order to prevent the sensor from heating by Joule effect.
