Soil moisture sensor module with alarm

The soil moisture sensor module with a built -in alarm allows automatic control over the proper hydration of plants and flowers. In the case of dry soil, the module launches a quiet acoustic alarm reminding about watering flowers. It also has a twilight sensor that excludes acoustic signaling at night (in this case the module signals the alarm with the LED).

Technical data:
Power supply: CR2032 battery (not included)
Total length: 140 mm
Measuring part length: 70 mm
Width: 15 mm

To start using the soil moisture sensor module with alarm:
Wait until the plant requires watering - in this way you will determine the minimum level of soil moisture needed to work the alarm signal.
Install the battery (pay attention to the polarization!)
Carefully press the sensor module into the soil (into the line shown on the device). Gently arrange the soil around the sensor so that there are no gaps between the sensor and the soil.
Press the button (located in the upper part of the sensor). During this operation, try not to move too much with the sensor. Do not touch the sensor, plant or pot for 5 seconds after pressing the button - the module needs some time for uninterrupted moisture level measurement.
Water the plant. Try not to pour too much water on the sensor module plate.
When the moisture level in the soil drops, the sensor signals this fact with an sound or optical signal (LED).

If the plant is too dry and the sensor is silent, carefully press the button without moving the device, wait 5 seconds and water the plant. In this way, the moisture sensor will be set to a new "too dry" level.
If the moisture sensor begins to make sounds when the soil is still too wet, pull the device out of the ground (for about 1 cm), press the button and insert the sensor back. Thicken the soil around the device.
