Soil moisture meters and testers

Analogue moisture meters work without batteries: you push the probe into the soil and the needle on the 1 to 10 scale shows how moist it is. Some models also measure pH from 3 to 8. Watering indicators 13 to 26 cm long signal dryness by the colour of their core, and the LED moisture meter by the colour of its light.

Digital soil testers with a backlit display measure 3 to 6 values depending on the type, such as soil pH, moisture, temperature and fertility, light or air humidity. 8-in-1 testers connect to your phone via USB, draw their power from it and also show EC conductivity and nitrogen, phosphorus and potassium content. The Bluetooth tester sends soil temperature and moisture to your phone.

Wireless soil sensors stay in the ground and send readings to the app via a gateway. 868 MHz sensors are IP66-rated with up to 100 m range, and the set includes a Wi-Fi gateway. Zigbee 3.0 sensors also monitor air temperature, humidity, light and in some cases fertility, but need a Zigbee gateway.
