In this project, we are going to build a Magnetic Polarity Detector using the Hall Sensor and LEDs. Here two Hall Effect sensors are used to detect the North Pole and the South Pole, and these sensors ...

The PIR motion sensor light wiring diagram is shown below. The basic idea is to amplify the output signal from the PIR sensor to control the relay, which, in turn, switches the bulb on or off. The ...

Object detection circuit Object detection circuit. Above is the object-detection circuit. The circuit can be divided into two parts: emitter and receiver. The emitter is composed of IR LED1 in series ...

Circuit diagram of the PIR Motion Sensor Light and Switch based on SB0061 shown here can be used for security or corridor lighting in power saving mode. The 12V DC supply required for the whole ...

Humidity Detector Circuit. October 26, 2013 by P. Marian ... You can use other sensors like LDR or NTC instead of the copper ones so you can use this circuit for detecting light or temperature.

During the operation, the circuit is producing a low output when sufficient lighting is received by the light detector. Even in the dark, a source of light can still be produced from many ways. The ...

This optical smoke detector uses a low-cost, readily-available, slotted, through-scan, infrared photo-switch. When smoke is detected, the relay energises to activate the audio/visual warning alarm.

The SPAD-based Light Detection and Ranging (LiDAR) sensor [1–3] has found widespread applications across various fields, including consumer electronics, surveillance, and autonomous driving [4].

In this work, an interface circuit for readout integrated circuit (ROIC) has been proposed employing source follower per detector (SFD) unit cell and current mirror integration (CMI) in order to have ...
