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 ...

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 ...

The MAX6612 precision analog output temperature sensor features a large change in output voltage with temperature change—19.53 mV/°C—for greater noise immunity than conventional temperature sensors.

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, ...

Chemical sensors can act as sentinels for explosive gases like hydrogen or methane or for harmful volatile organic compounds before they build to dangerous levels. But typically, they can only sound ...
