But it would start throttling at 82 degrees celsius. In this article i will show you how to monitor the temperature of your raspberry pi. There are two different types of thermistors. Thats the maximum limit. Raspberry pi is a low end mobile computer. To retrieve the temperature of your raspberry pi we can utilize the following command.

The pimoroni fan shim is a great solution for reducing the temperature of your pi when it runs hot. The following will show you how to build and program the raspberry pi to use a thermistor to take temperature measurements of a room. Precise temperature control on the raspberry pi 4. Description of the 1 wire raspberry pi temperature sensor the temperature sensor returns a 9 to 12 bit long value which can be read and converted. The makers even provide software that triggers the fan when the cpu temperature rises above a certain threshold eg. The ds18b20 temperature sensor is perfect for projects like weather stations and home automation systems.

Negative temperature coefficient ntc and positive temperature coefficient ptc. Theyre also extremely accurate and take measurements quickly.
