This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very ...

The temperature sensor is built using an NTC 10k thermistor, which changes its resistance in response to changes in temperature. The resistance of the thermistor is measured using the Arduino's analog ...

Read environmental data (temperature, pressure, humidity, and gas resistance) from a BME680 sensor using Arduino UNO. Send the sensor data over the CAN Bus using an MCP2515 CAN controller module.

I used an LCD shield to display the current temperature and speed of the fan, but you can use the circuit without the LCD display. You also need to select the transistor by the type of fan that you ...
