RainPoint SM-021-2024 3-in-1 APP Remote Monitoring WiFi Soil Moisture Meter for Plants Indoor/Outdoor: Real-time monitoring of soil moisture, temperature, and light intensity
For the plant parent who juggles a busy schedule, this sensor is your remote green thumb. It lets you check soil moisture, temperature, and light for your indoor herbs or outdoor garden beds from your phone, so you never second-guess if your plants need water while you're at work.
Think of it as a proactive plant nanny, not just a data tool. The custom alerts ping you when moisture dips below your set level, so you can water before leaves droop. In our test, the light sensor caught a shift when a cloud passed over, helping us move a sun-loving succulent to a brighter spot.
Pair it with a RainPoint hub and water timer to build an auto-watering system that adjusts based on real-time soil readings. This Alexa-compatible setup ensures your plants thrive with precise care, saving you time and guesswork.
