This article explains an upgraded smart solid-state AC switch system that uses microwave Doppler radar instead of traditional PIR sensors.

A way to apply the output of certain sensors to a TTL/CMOS-level iput on a microcontroller. Sensor must have an NPN output stage that can support a pullup to its power rail. With just a few components ...

Dc photoelectric sensors detect the presence or absence of light. When outputs turn on, power flows through the load. When turned off, the load receives no power. The remaining two modes of operation ...

Digital sensors that include the ADC and output digitized data via RS-232 or RS-485 using various protocols have been practical for several years. According to Mokhberi, “The potential for mass appeal ...

The LMT87/LMT87-Q1 are precision CMOS integrated-circuit temperature sensors with an analog output voltage that is linearly and inversely proportional to temperature. Its features make it suitable for ...

DW Series round metal inductive proximity sensors with analog outputs are now available from AutomationDirect in 8mm, 12mm, 18mm and 30mm cylindrical sizes. These reliable DC-powered (10-30V or 15-30V ...

While conditioning is necessary for measurement precision, accuracy also relies on factors such as signal transmission and sensor construction. The transmission distance can affect the signal quality, ...

The wearable sensor market is growing at an annual compound rate of 17.8%. However, sensors have challenges, particularly in terms of miniaturization and power consumption. Several key parameters are ...
