JungleSIM M1S Soil Moisture Sensor
Controlling devices needs an S1M or C1H
To see the readings, the sensor alone is enough: in Wi-Fi mode it sends them straight to the app over your 2.4 GHz home Wi-Fi. As soon as JungleSIM should control a device by them (heater, mister, fan, pump or any other device), you need a controller: the S1M screen module or the C1H control hub.

The M1S goes into the substrate and tells you how moist it is, so you know whether the plants need water or the ground is getting waterlogged. It measures capacitively, with no bare metal touching the soil, so it does not corrode in a wet terrarium. It sends its readings to your S1M or C1H without a cable.
Only want to see how moist the soil is? Then the M1S alone is enough. In Wi-Fi mode it sends its readings straight to the JungleSIM app over your home Wi-Fi, every few hours, so the battery lasts for months. As soon as JungleSIM should control something, like your rain system or any other device, you need an S1M or C1H. You can move the sensor from one mode to the other in the app at any time.
It works just as well in a house plant: see JungleSIM for plants.
JungleSIM is the control side: controllers and sensors. It does not replace your lights, heaters, pumps, foggers or other devices; it switches the ones you already have through Shelly smart plugs.

Product safety
Only the probe blade goes into the substrate, up to the SOIL LINE mark; the case is made for humid terrarium air but is not waterproof: don't bury or flood it, keep the dust plug in the USB-C socket. Contains a rechargeable lithium battery: charge it only outside the terrarium, when dry, at 0-45 °C, with a CE-marked 5 V USB-C power supply to EN IEC 62368-1; don't puncture, crush or heat it, and stop using it if it swells. Don't rely on it alone for watering. Not a toy (small parts). Don't open or modify it except to change the battery. Electrical devices and batteries don't belong in household waste.
