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 ...

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 ...

A compensated Pt100 RTD circuit has 1 mV/°C DMM output, with linearization via positive feedback, pending Part 2 ...

How often have you pulled out old MCU-based project that still works fine, but you have no idea where the original source ...

MEMPHIS, Tenn. — Watch out for sprinkles this morning. It's a cloudy and cold start to the day. Temperatures this afternoon will rise to the mid-60s across the Mid-South. AM rain chance: 10%. Winds: ...

Abstract: A highly sensitive and stable temperature sensor based on a diamond-Ga2O3 Schottky-p-n diode is demonstrated in this work. The forward current exhibits a pronounced temperature dependence, ...

Abstract: In this work, we present a high-sensitivity fiber-optic temperature sensor based on the enhanced Vernier effect. The sensor consists of a cascade of three Fabry–Perot interferometers (FPIs), ...

This library can be used with Arduino IDE 1.6.6 (or above) to add one or more joysticks (or gamepads) to the list of HID devices an Arduino Leonardo or Arduino Micro (or any Arduino clone that is ...

This is a copy of the json payload sent from the mqtt publisher application. The object id's are used to build the HA sensor id's. The id value affects the HA sensor parameters. exclude_sensor and ...
