A complete embedded system project for intelligent plant hydration and environmental management. PlantWise integrates STM32-based hardware, a Raspberry Pi MQTT broker, and an Android app for real-time ...

The upgrades start with the image sensor. This time around, instead of using a generic Raspberry Pi camera, he’s gone with the fancier ArduCam OwlSight sensor.

A Raspberry Pi Pico runs the show, using TMC2209 drivers to command a pair of NEMA17 stepper motors to drag a magnet around beneath the sand.

The soil system is complex and dynamic, making it difficult to understand using traditional statistical approaches. In this paper, we analyze the causal relationship of soil temperature and moisture ...

In this paper, we present the design, fabrication and calibration of a passive UHF RFID tag based soil moisture and environment temperature sensor. The inter-digital double-sided capacitive sensor ...

A lightweight Raspberry Pi sensor logger in Python for HC-SR04 (ultrasound) and DHT11 (temperature/humidity), exporting data to CSV or Google Sheets. Perfect for IoT experiments, smart home logging, ...
