Raspberry pi water temp sensor. But you can also switch several sensors in series because it is based on the 1 wire protocol. Wiring of the temperature sensor. However this is so far only possible on gpio pin 4 pin 7. To be able to retrieve the temperature of the raspberry pi you will need terminal access.
First we need to alter the raspberry pi s config file to enable the 1 wire interfacing use by this sensor. The raspberry pi can also be used as a micro controller but it has a lot more functions because it runs an operating system. Amazon s choice for raspberry pi temperature sensor. Description of the 1 wire raspberry pi temperature sensor.
Luckily for us the raspberry pi s processor features an inbuilt temperature probe that we can access. 1 16 of 564 results for raspberry pi temperature sensor price and other details may vary based on size and color. The raspberry pi temperature sensor code. 381 this is a pre wired and waterproofed with heat shrink version of the ds18b20 sensor.
The temperature sensor returns a 9 to 12 bit long value which can be read and converted. The code for setting up the temperature sensor is a little more complicated than the circuit itself. Once you have access to the terminal through ssh or physical access then you can proceed. Handy for when you need to measure something far away or in wet conditions.
It can for example also read analog sensors. While the sensor is good up to 125 c the cable is jacketed in pvc so we suggest keeping it under 100 deg c. This complexity is just because of the way we need to handle the data that comes from the sensor. A true micro controller is e g.
