The 7Semi SHT40 Tiny Board is an advanced, space-saving solution engineered for precise environmental monitoring, combining cutting-edge sensor technology with ultra-low power consumption. Equipped with the fourth-generation SHT40 humidity and temperature sensor, this board ensures high accuracy and efficiency, making it an essential tool for embedded systems, IoT deployments, and smart automation solutions. The sensor delivers 16-bit resolution, allowing fine-grain measurements that support reliable data analysis across a variety of demanding applications.
Supporting an I2C interface with preconfigured address options, the board is optimized for seamless integration, especially with Qwiic-compatible modules. Its typical relative humidity accuracy of ±1.8% (25%–75%) and temperature accuracy of ±0.2°C (0°C–75°C) guarantee consistent performance even in varying environmental conditions. The 4-pin 1mm pitch connector ensures compact, solder-free connectivity, ideal for developers seeking robust and scalable sensor solutions in constrained spaces. Operating at 3.3V with power consumption under 0.15mA, it’s perfectly suited for battery-powered devices, mobile sensors, or edge devices in smart infrastructure networks.
