Plant monitoring HAT for Raspberry Pi 4 model B with light intensity, temperature, humidity, CO2 sensing, and camera attachment

2Cell Battery Charger & A9G Module

Welcome to your new project. Imagine what you can build here.

Smart Thermostat design using an ESP32 module for WiFi connectivity and a BME680 sensor for environmental monitoring. The user interface includes an E-ink display and an encoder for settings adjustment. Power: USB and Battery Movement sensor

Shield for measuring voltage/current using three ACS712s. The shield is suitable for your IoT devices where power monitoring is required, such as a solar station

Mobile Hydraulic Fluid Filtration Test Bench with 220VAC Power, 24VDC Isolated Controls, ESP32 Monitoring, and Safety Interlocks

HVAC System controller board. Features 4 10A250VAC relays (For power control), a BME680 for environmental monitoring and a 5v-35v driver to control up to 2 DC motors. #esp32 #iot

This is a voltage/current monitoring board based on the ACS712. There are as many as three voltage monitoring chips, which makes the board versatile for a lot of projects #esp32 #ACS712 #IoT #monitoring
