Here are some DIY LDR switch circuits available on our website and the web. LDR switches are used to switch a relay or other device when light are present or absent. LDRs or Light Dependent Resistors ...

LDR sensors are placed on street lights and detect ambient light levels. When the sunlight is still bright, the LDR resistance is low due to the high light to save energy. Conversely, at night, when ...

General purpose circuit of the simple pressure sensor alarm is built around a couple of readily available cheap components. Working of this circuit is straight forward and self-explanatory. When the ...

Thermistors are used as temperature sensors, for example, in fire alarms. Their resistance decreases as the temperature increases. At low temperatures, the resistance of a thermistor is high, and ...

When most of us think of glove controllers, the first which comes to mind is Nintendo’s PowerGlove, which promised much more than it delivered. But the idea persists, and from time to time we see them ...

Abstract: This work deals with the estimation of global solar irradiance in an embedded platform through the use of a Light Dependent Resistor (LDR) sensor and its temperature. A prototype is built ...

This project involves building a Wireless Sensor Network (WSN) using Arduino boards to monitor various environmental parameters such as temperature, humidity, light intensity, and air quality. The ...
