Product Description

Small plate with a microcontroller or control device interface specification (4-wire)

1 VCC 3.3V-5V external

2 GND External GND

3 DOUT small board digital output interface (0 and 1, the comparator output)

4 AOUT small board analog output interface (direct analog output interface)

 

    Wherein, VCC and GND must be connected correctly, use the analog output AOUT is connected to the microcontroller or external A / D chip A / D input pin, then use the switch DOUT connected directly to the microcontroller I / O pin or relay to volume control on the device.

 

    Note, DOUT and AOUT may not be used simultaneously, can also be used at the same time, all depending on your needs.

 

Small board input interface specification (2-wire)

 

    Connect an external sensor or probe is part of a small straight pin board two lines

 

1, for no polarity probes, such as sensing probe raindrops, soil sensing probes, probe directly to the two lines can be connected to two needles, no positive and negative;

 

2, the polarity of the probe, such as infrared sensing probe, phototransistor, etc., the probe connected to the positive terminal marked "+" sign of a needle probe connected to the negative terminal of another needle, in general, similar to the LED positive probe legs, short legs is negative.

 

Sensitivity adjustment:

 

    Rotation of the potentiometer can be. In general, infrared sensing probe is adjustable sensing distance threshold, sensor adjustment is to detect soil moisture soil moisture threshold.
