In this particular project, I contemplated a shield for Arduino Nano, which can gather weather-related information by a built-in BMP280 Temperature and Pressure Sensor, a photoresistor, and a ...

The system here monitors temperature, humidity, and smoke levels and alerts you if those levels reach a certain point.

Arduino & AHT10 Next, I wired up AHT10 sensor module and Arduino Uno as shown in the below hardware setup diagram. I also uploaded a simple test code to display sensor readings on the Serial Monitor ...

By the way, we’ve covered a PID library for Arduino before. While this post talks about temperature, PID control is used for everything from flight control to levitation.

There’s an Arduino with a custom shield that interfaces the barometric pressure sensor, real-time clock chip, a digital temperature sensor, and a humidity sensor.
