This project collects temperature and humidity data using a DHT22 sensor connected to an Arduino. Data is sent via a Python bridge to a Flask backend, which validates and stores it in MongoDB. The ...

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

This project demonstrates how to control a fan (simulated with an LED) using an Arduino Uno and a temperature sensor. Below 25°C → Fan OFF 25°C to 30°C → Fan runs at 50% speed (PWM) Above 30°C → Fan ...

Those of you that are looking for a temperature datalogger may be interested in a new piece of kit which has arrived at the Adafruit website this week in the form of the Pax Instruments T400 ...

Designing an analog circuit can be a frustrating experience, as noted by Nick Cornford in his Design Idea (DI), “DIY RTD for a DMM.” With a fortnight’s struggle, I completed the design of 4 mA to 20mA ...
