Humans spend about 80% of their time indoors, but keeping track of the air we breathe usually requires expensive lab-grade ...

The PIR library implements a class to monitor 1 or more PIR sensors. The library supports default 8 PIR sensors per object, which typically are added in setup(). It is possible to add a sensor (pin) ...

Monitor your property day and night with one of the best smart floodlight cameras we've tested. I'm PCMag's managing editor for consumer electronics, overseeing an experienced team of analysts ...

Engineers have made bacteria to produce hyperspectral signals that can be detected as far as 90 meters away. Their work could lead to the development of bacterial sensors for agricultural and other ...

The library gives control over up to 16 parallel working PIR devices over I2C. The idea for this library came up in a discussion about how to fully cover an area with PIR sensors without blind spots ...

Abstract: This paper presents the use of the Proteus environment for the study of Arduino-driven sensor circuits, designed to support electronics student education. A simulation model of sensor ...

A sensor signal conditioner (SSC) is an integrated circuit that improves — or conditions — the signal coming from a sensor to reduce noise. The SSC also converts the signal from analog to digital ...

Abstract: These days, three modules are expected to be used to control the lights and fans in the classroom. The common sensors are used in situations where the energy safety and efficiency of the ...

The Bee Motion S3 is an ESP32-S3 WiFi and Bluetooth IoT board with a PIR motion sensor beside the more usual I/Os, Qwiic connector, USB-C port, and LiPo battery support. It is at least the third PIR ...
