HONG111 5pcs TE215 Dual Mode High Sensitivity Soil Moisture Sensor, Auto Arduino Sensor Module Watering System Manager 3.3V-5V

HONG111 5pcs TE215 Dual Mode High Sensitivity Soil Moisture Sensor, Auto Arduino Sensor Module Watering System Manager 3.3V-5V

• Operating voltage: 3.3V-5V
• Module Output is high level when the soil moisture deficit,or output is low
• Can be used in module plant waterer device, and the plants in your garden no need people to manage
• This is a must have tool for a connected garden! It will be helpful to remind you to water your indoor plants or to monitor the soil moisture in your garden.
• Module dual output mode, digital output, analog output more accurate.

<p><b>Specification:</b><br><p> Operating voltage: 3.3V~5V.<br> Adjustable sensitivity (shown in blue digital potentiometer adjustment)<br> Dual output mode-analog output more accurate.<br> A fixed bolt hole for easy installation.<br> With power indicator (red) and digital switching output indicator (green).<br> Having LM393 comparator chip- stable.<br> Panel PCB Dimension: 3cm x 1.5cm.<br> Soil Probe Dimension: 6cm x 2cm.<br> Cable Length: 21cm.<br> VCC: 3.3V-5V.<br> GND: GND.<br> DO: digital output interface(0 and 1).<br> AO: analog output interface.<br> <p><b>Attention:</b><br><p> 1. Soil moisture module is most sensitive to the ambient humidity is generally used to detect the moisture content of the soil.<br> 2. Module to reach the threshold value is set in the soil moisture- DO port output high- when the the soil humidity exceeds a set threshold value- the module D0 output low.<br> 3. The digital output D0 can be connected directly with the microcontroller to detect high and low by the microcontroller to detect soil moisture.<br> 4. The digital outputs DO shop relay module can directly drive the buzzer module- which can form a soil moisture alarm equipment.<br> 5. Analog output AO and AD module connected through the AD converter- you can get more precise values of soil moisture.<br> <p><b>Package Included :</b><br><p> 5 pcs Soil Moisture Detector Module<br> 5 Set of Jumper Cables (2 in 1)<br>
