New Soil moisture meter to detect soil moisture sensor module robot smart car
A description of the baby
1 This is a summary of the moisture sensor can be used to detect soil moisture , soil water when the module outputs a high level , whereas the output low. Using this sensor make an automatic watering system , so that your garden plants need people to manage .
2 adjustable sensitivity ( shown in blue digital potentiometer adjustment )
4 Operating Voltage 3.3V-5V
5 module dual output mode, the digital output is simple, analog output is more accurate.
6 with fixed bolt hole for easy installation
7 small PCB board size : 3cm * 1.6cm
8 power indicator ( red ) and digital switching output indicator ( green )
9 using LM393 comparator chip , stable
Two small plate interface specification ( 4-wire )
1 VCC 3.3V-5V external
2 GND GND External
3 DO small board digital output interface ( 0 and 1 )
4 AO small plates analog output interface
Three instructions
A module for soil moisture humidity most sensitive , generally used to detect soil moisture .
2 module in soil moisture reach the set threshold , DO port output high, when soil moisture exceeds the set threshold, the module D0 output low ;
3 digital outputs D0 small plates can be directly connected to the microcontroller through the microcontroller to detect high and low , thereby detecting soil moisture ;
4 small plates digital output DO OUR relay module can directly drive the buzzer module, etc. , which can form a soil moisture alarm equipment ;
5 small plates AO analog output modules can be connected to the AD , by the AD converter , you can get a more accurate value of soil moisture;
