Introduction There are different sensors and methods for determining water depth, leakage, whether a container is empty or overflowing, and rain detection. One of the easiest and cheapest methods is to use a water level detection sensor that we will discuss in this tutorial.There are some other common names for this sensor: rain sensor, water level sensor, humidity sensor, and water leakage sensor. What you will learn Operating principles of a water level sensor and how to test itInterfacing th...

What is AM2301 Sensor? The AM2301 module is an internally-calibrated digital sensor that measures temperature and humidity. It can measure humidity from 0 to 99.9% with an accuracy of ±2% and temperatures from -40 to 80°C with an accuracy of ±3°C.This digital module uses a single-wire protocol for communication. So, apart from the power supply pins, it only needs one digital pin to communicate with the microcontroller. Using this protocol, we can transfer data through this line for a maximum distanc...
