Capacitive Soil Moisture Sensor with Buzzer
₵50.00
In StockIndependent soil moisture sensor with built-in buzzer that gives a warning when the humidity is low.
The sensor distinguishes itself from other soil moisture sensors by the capacitive measurement instead of a resistance measurement. This makes the sensor a lot more corrosion-resistant and therefore lasts longer.
Specifications:
- Input voltage: 3VDC via a CR2032 button-cell battery (Note: the battery is not included, but is sold separately)
- Size: 140x15mm

Solar panels are a clean and ecological source of electricity. Obtaining this energy, however, poses several challenges for device designers. The amount of energy produced by the panel is strongly dependent on the angle of incidence and the intensity of the light falling on the surface of the cells. This, in turn, leads to unstable power supply parameters at the output, as even shading a small part of the panel may drastically reduce the efficiency
The optimal solution to the above-mentioned problems is the use of a set consisting of a solar panel, a battery and a charge controller. Such a set allows to ensure constant parameters of power supply to receivers and also to store energy produced excessively for later use
The SCC-30A-PWM-LCD solar charge controller allows you to connect panels both in series and in parallel – remembering not to exceed the permissible values of current and voltage at the input of the device. Due to the operating characteristics of the PWM controllers, it should be remembered that when the panels are connected in series, the rated voltage at the output for charging the battery is 24V.
