Arduino Modulino® Thermo
Arduino Modulino® Thermo is a compact, plug-and-play temperature sensing module built around the HS3003 humidity and temperature sensor. Offering high accuracy (±0.5 °C typical) and low power consumption, the Modulino Thermo is ideal for indoor climate control, greenhouse monitoring, and smart home automation. With Qwiic and 5-pin connectors, the module integrates easily into Arduino and third-party ecosystems, enabling fast prototyping and reliable thermal data acquisition. A small form factor and I2C interface make the device a practical solution for embedded designs requiring precise, real-time temperature feedback.Features
