Additional Information:

• Item Code: RS085

Product Details:

The module is based on a touch-sensing TTP223B Digital Touch Sensor Module. In the normal state, the module output low, low power consumption; When a finger touches the corresponding position, the module output high, if not touched for 12 seconds, switch to low-power mode.

Features:

• Low power consumption
• Can replace the traditional touch of a button
• Four M2 screws positioning holes for easy installation

Additional Information:

• Item Code: RS098

Description:

• 100% Brand New and High Build Quality
• This is a simple water sensor can be used to detect soil moisture when the soil moisture deficit module outputs a high level, and vice versa output low. Use this sensor produced an automatic plant waterer device, so that the plants in your garden without people to manage.
• Sensitivity adjustable the blue digital potentiometer adjustment
• Module dual output mode, digital output, analog output more accurate

Instructions for use:

• Soil moisture module is most sensitive to the ambient humidity is generally used to detect the moisture content of the soil.
• 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.
• The digital output D0 can be connected directly with the microcontroller to detect high and low by the microcontroller to detect soil moisture
• The digital outputs DO shop relay module can directly drive the buzzer module, which can form a soil moisture alarm equipment; Analog output AO and AD module connected through the AD converter, you can get more precise values of soil moisture.

Package Includes:

• 10 pcs Soil Humidity Hygrometer Moisture Detection Sensor Module Arduino

Additional Information:

• Item Code: RS012
