Rain Detection Sensor Module Circuit Diagram The schematic diagram for the Rain Detection Sensor module is shown below. The schematic itself is very simple and needs a handful of generic components to ...

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.

This is a very simple touch sensor switch that is build with the 555 timer IC. You just need to touch the metal plate and the relay gets energised and is kept in this state for about 100 seconds, then ...

A low-cost, high-sensitivity, 2-D displacement sensor based on the alignment of a single-mode fiber (SMF) and a four-core fiber (FCF) has been proposed. The emission light from the SMF is irradiated ...
