In this video, I'm exploring the use of Mini PIR Sensors with ESP32 with both Arduino-based projects as well as making a movement sensor for Home Assistant by using ESPHome. The sensor is quite ...

BMV080 is a low-power, low-cost PM1, PM2.5, and PM10 sensor module with I2C and SPI interfaces that sells for just $29.90.

In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...

If you're savvy and want to do a bit more home monitoring, these interesting sensor ideas might be worth trying.

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 ...

A comprehensive IoT-based HVAC control system featuring dual-microcontroller architecture (Arduino R4 Minima + ESP8266), web interface with Flask, real-time monitoring via DHT22 sensor, IR control for ...

Abstract: This study presents a reference-free calibration method for wearable core body temperature sensors based on the single-heat-flux approach, eliminating the need for a pre-constructed dataset ...

Abstract: Global warming and the associated increase in heatwaves have made the prevention of heat-related illnesses such as heatstroke a critical global challenge. Monitoring physiological indicators ...
