Presented here is an automatic motion sensor switch built around a cheap ‘Doppler Microwave Radar Sensor’ that can be easily used as standalone detection sensor. The circuit, designed as an alternative to the common PIR motion detectors, is perfect for DIY microwave motion sensor light switch, human sensor alarms, smart security devices, etc. The given… [Read More]
Different Types of Sensors – Analog and Digital
Sensors have become an integral part of the embedded system. Right from your mobile to security systems installed at home. They are also becoming important for meteorological stations to predict weather parameters like temperature, pressure, humidity, and many more. To interface any sensor to the microcontroller, you have to know the function of the sensor… [Read More]
