Item Description

This pair of SCD40 sensor modules combines temperature and humidity measurement into a single compact package. Each module handles both readings simultaneously, making it ideal for weather stations, environmental monitoring systems, or any project requiring dual environmental data collection. The SCD40 uses proven sensing technology to deliver accurate readings across a wide operational range. The modules measure approximately 17.5 × 10.5 × 11.5 mm, small enough to integrate into tight spaces while remaining robust enough for reliable performance. Communication happens through I2C protocol, which simplifies wiring and integration with microcontroller platforms like Arduino, Raspberry Pi, or similar development boards. The modules operate from 3.3V to 5.5V, giving you flexibility in power supply options. You get two complete units in this package, so you can build redundancy into your system or set up multiple monitoring points simultaneously. Whether you're building a greenhouse controller, indoor air quality monitor, or weather data logger, having two sensors lets you compare readings or expand coverage. The modules integrate easily with standard prototyping platforms, and plenty of example code exists online for quick implementation. Temperature sensitivity and humidity response are consistent across both units, making them suitable for applications where measurement uniformity matters.
