HX710B Air Pressure Sensor Datasheet, How to Connect
The HX710B Air Pressure Sensor Module monitors the air’s pressure in the range of 0 to 40 kilopascals (kPa) and turns it into an electrical impulse which microcontrollers or other electrical gadgets can interpret and read. It is a common and frequently utilized sensor in a wide range of applications that demand precise pressure sensing, […]
Smart Street Lamp Circuit with Motion Sensor
This simple yet highly sophisticated, smart LED street light circuit automatically switches ON a street lamp from low brightness to high brightness whenever it detects a moving object underneath it. This action is initiated only during nighttime, while during daytime the street lamp remains completely shut off. What this Circuit will do This advanced automatic […]
