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 ...

Abstract: Passive infrared (PIR) sensors are widely used in motion sensing and lighting control. However, stationary occupants always trigger false-negative detects of PIR sensors and result in ...

Passive infrared (PIR) sensors are experiencing sustained growth in 2026. This is driven largely by the expansion of smart home technology, building automation, and energy-conscious design. Once ...

Panasonic Industry unveils a new generation of passive infrared (PIR) motion sensing arriving with a clear message: performance no longer needs to come at the cost of design. A recently introduced ...

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 ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

A slew of wireless and increasingly multi-modal sensors is being targeted at the Industrial Internet of Things (IIoT), setting the stage for significant improvements in efficiency, higher yield, and ...

This is a library for the Arduino IDE that helps interface with ST's VL53L4CD time-of-flight distance sensor. The library makes it simple to configure the sensor and read range data from it via I²C.

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 ...

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 ...

From controlling everything from door locks to energy consumption, smart home technology has taken the world by storm. But can smart home appliances solve another pesky and common issue: pest control?
