Foton is a special lightsaber, which can monitor temperature and humidity of a room, detect movements, and send those data to a smartphone.

Simple weather station Arduino UNO: measures temperature, humidity, air pressure using BMP280, DHT11, windspeed 3D-printed anemometer.

With so many temperature sensors available, how should we choose the right one for our Arduino project? Well, it really depends on several factors such as what we are measuring, the degree of accuracy we need and where we may be measuring the temperature.

Different temperature and humidity sensors have large performance differences and large price differences. So how to choose the most suitable sensor for your project?

Looking for low-cost temperature and humidity sensors? DHT11 and DHT22 are the most common temperature and humidity modules for Arduino and Raspberry Pi. DHT sensors will be perfect for you. Despite being slower than other temperature sensors, they have advantages including low power consumption and excellent long-term stability.
