Simple Light Sensor Circuit Features High Dynamic Range. Dec. 13, 2009. Shyam Sunder Tiwari. Ambient light is increasingly being used as a source of energy.

This is a very simple touch light switch circuit that uses the 4011 IC, one transistor and a relay. The C1 capacitor stores the switching state at a certain time and is charged or discharged according ...

Needless to say, a simple add-on hardware is necessary for this little experiment. The hardware is nothing but an ambient light sensor circuit wired around the silicon NPN epitaxial planar ...

I just had this exact circuit on my breadboard twp days ago and could get the led to light fine, but had trouble using it to control a 4066 input pin. any advice would be appriciated thanks ...

Although this circuit connects the DS18S20 1-Wire temperature sensor to a Cypress CY8C26443 PSoC microcontroller, designers can easily adapt it to connect other 1-Wire devices to any microprocessor.

Researchers have developed a new optical sensor that provides a simple way to achieve real-time detection of extremely low levels of arsenic in water.
