Crowtail-Capacitive Moisture V2.0 is a durable soil-moisture sensor based on capacitive technology, ideal for monitoring plant hydration levels. Intended for use in projects with 3.3–5 V microcontrollers.

The module allows to measure the occurrence and strength of precipitation (rain), has an LM393 system and an adjustable threshold for the digital output.

A compact Hall-effect current sensor that provides accurate DC and AC current measurement within a ±30 A range with galvanic isolation. It features an analog VOUT output with a sensitivity of 66.7 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 5443
