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 ...

Abstract: Design and development of a novel smart chipless humidity sensor tag has been proposed. A key approach introduced in this article for the first time is to utilize ground plane chipless radio ...

This guide shows you how to build a motion detection system that sends instant WhatsApp alerts using the compact XIAO-ESP32 development board. When the IR sensor detects movement, the board ...

Abstract: A surface plasmon resonance (SPR) sensor based on a polyvinyl alcohol-graphene oxide (PVA-GO) composite film and a polydimethylsiloxane (PDMS) film was proposed for simultaneous measurement ...

Python implementation of the SensorPush temperature and humidity/hygrometer sensors cloud API which supports both temperature (°F) and humidity (Rh) sensors. NOTE: Ideally SensorPush sensors would be ...

Easy-to-use interface for configuring and reading radar data. Supports both single and multi-target detection modes. Works with Arduino-compatible board that has a separate hardware UART.
