The 5 Best rain Moisture sensors (2023 reviews)

Ecowitt makes beautiful and outstanding sensor with classic and higher-grade materials. If you want to know when your garden needs water this sensor will help. It is perfect for trees/5gal+ pots. It is made of gold-plated copper and is made inside the pcb. Each gateway handles up to 8 moisture sensors, so if you plan on having more moisture sensors than 8, then you'll need more gateways. It is great for reviewing live & previous data.

The wimpy batteries that come in the lights are actually sufficient to keep the minuscule power demands of the moisture sensors happy in the dark. It's not difficult and only takes about 10 minutes to prepare a saturated soil and a dry soil for calibration.

Why We Like This:

Sleeps most of the time, conserving battery
Particularly useful for monitoring areas where it is impractical to use a manual tester
Works with good range and excellent battery length
Enabling the gateway to transmit to weather services unlocks more power
