Inside this tiny package is a beautifully-spun board with an ESP32 Pico D4 for a brain. In addition to the climate sensors there is a combination CO2/TVOC sensor (that’s total volatile organic ...

A second set of sensors keeps track of the temperature of the water and the outside air, which should help in finding insulation failures and keeping energy use under control. An ESP32 reads the ...

Pico-DALI2 Expansion Module for ESP32-Pico enables DALI communication for smart lighting control and automation systems.

Vibration sensors are sensors for measuring, displaying, and analyzing linear velocity, displacement and proximity, or acceleration. Vibration — however subtle and unnoticed by human senses — is a ...

You can save a lot of money and hassle by installing a smart water sensor. The best models we've tested immediately alert you to leaks and even shut off the water ...

Both sensors measure rate of change; they just measure the rate of change for different things. In practice, that means that an accelerometer will measure the directional movement of a device but ...

Pressure sensors include all sensors, transducers and elements that produce an electrical signal proportional to pressure or changes in pressure. The device reads the changes in pressure, and then ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level ...

We liked the YoLink Smart Window Door Sensors, LoRa ¼ Mile Range best and were impressed with its ability to transmit up to a quarter of a mile away. The best alarm for a particular shopper will ...

Sensors are devices that detect and quantify physical aspects of the world around us. The measurement can either be read directly or converted to a signal for processing by electrical, hydraulic ...
