Light aircraft often use a heading indicator as a way to know where they’re going. Retired instrumentation engineer [Don Welch] recreated a heading indicator of his own, using cheap ...

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 ...

The hardware setup shown below includes the Arduino Uno R4, a DHT11 sensor, and the built-in Wi-Fi for email alerts. The DHT11 is connected with VCC to 5V, GND to ground, and the data pin to Digital ...

This section defines the network credentials and server details required for sending the email. The ESP32-CAM connects to WiFi using the SSID and password. The host address, HTTPS port (443), and API ...

Panasonic Industry has announced its latest PIR (passive infrared) motion detector, a Flat Wide Detection Type (12 lens) sensor. It includes PaPIRs+ (Panasonic Passive Infrared Sensors+), the ...

Aqara is introducing a new presence sensor that is a natural addition for HomeKit users who want reliable automations without the need for a camera. The new Aqara FP300 combines mmWave presence ...

Before SwitchBot entered the robot vacuum market, the smart home devices manufacturer was into simple, affordable retrofit solutions that made traditional appliances ...

As radar technology continues to advance, it offers an increasingly broad range of capabilities, making it a viable alternative to traditional passive infrared (PIR) sensors. With radar’s enhanced ...

The FP1E’s millimeter wave technology provides for a much more nuanced look at whether a room is occupied or not, but you’ll need one of Aqara’s Zigbee or Matter smart home hubs to use it. Whatever ...

A new motion sensor incorporates micromachined thermal transistors to facilitate human presence and motion detection in security systems, home automation equipment, and Internet of Things (IoT) ...
