A Capacitor is connected across the output pin so as to filter out any noise coming from the sensor. Relay Module - Relay module is used to actuate the fan, The reason behind using relay module is fan ...

This package starts a Domapic Module that handles a 3 or 4 way switch made with relays. It is intended to be used in a Raspberry Pi or any other system supporting the onoff library, such as C.H.I.P.

The module I received was marked “485 Relay 2CH V1.1” on the top. There’s a AMS1117-3.3 (www.advanced-monolithic.com) LDO voltage regulator (3.3V), a Shenzhen Hangshun Chip Technology Development ...

Circuit operation. Circuit diagram of the IR motion sensor relay switch is shown in Fig. 2. It is built around a PIR motion sensor module (connected across CON2), MOSFETs BS170 (T1) and IRF9540 (T2), ...

Relay node placement problem is a very well-known problem of Wireless Sensor Networks. Many techniques (heuristics and algorithms) have been proposed to solve this problem. However, few ...

Sensor nodes can fail for various reasons, such as battery depletion, faults in the communication module, and faulty processor module. Some environmental factors can also cause node failure. This ...
