I introduction
1 this is a simple water sensor that can be used to detect soil moisture. when soil is short of water, the module outputs a high level and vice versa.Use this sensor to make an automatic watering device so that plants in your garden don't have to be managed.
2 sensitivity adjustable (blue digital potentiometer adjustable)
4 working voltage 3.3v-5v
5 module dual output mode, simple digital output, more accurate analog output.
6 with fixed bolt holes for easy installlation
7 small plate pcb size: 3cm x 1.6cm
8 power supply indicator (red) and digital switch output indicator (green)
9 comparator uses lm393 chip and works stably
Specification of interface for two small panels (4 line)
1 vcc external 3.3v-5v
2 gnd external gnd
3 do small board digital output interface (0 and 1)
4 ao small board analog output interface
Iii. description of use
1 soil moisture module is most sensitive to environmental humidity and is generally used to detect soil moisture.
Module 2 output high-level when soil moisture does not reach the set threshold, module d0 output low-level when soil moisture exceeds the set threshold
3 small board digital output d0 can be directly linked to single chip computer, through single chip computer to detect high and low level, so as to detect soil moisture
4 small board digital output do can drive the relay module, buzzer module, etc. directly, so can form a soil humidity alarm device
Ao can be connected to ad module, and more accurate soil moisture can be obtained by ad conversion
Iv. shipping list
1 set of finished boards (including testing boards and soil moisture probes) for the soil moisture testing module as shown in the figure
2pcs 20cm dupont cable for easy w
