Temperature and humidity sensor adapted to work with Sonoff TH10 / TH16

Pressure sensor module with I2C interface (BMP085)

A compact Hall-effect current sensor that provides accurate DC and AC current measurement within a ±10 A range with galvanic isolation. It features an analog VOUT output with a sensitivity of 200 mV/A and a 150 kHz bandwidth, enabling fast and precise readings in dynamic systems. The module operates over a wide temperature range of -40°C to 125°C, and the low current path resistance (~1.6 mΩ) minimizes energy loss. Its small size and flexible mounting options make it ideal for prototyping, industrial systems, and space-constrained projects. Pololu 5442
