Schematic
The factory heavy attack : the module soil moisture detection, transmitted to the microcontroller, and programmable control relays, arbitrarily set the delay time, delay the pull delay conduction delay-off can be optocoupler isolation, stable performance, wide operating voltage 5V-12V .
[Usage]
Soil moisture is automatically detected by the potentiometer adjustable the soil humidity valve point, and comes with the relays and programmable delay function, do automatic plant waterer device
[Module features]
1 programmable microcontroller soil moisture detection and delay.
Wide input voltage range of 5V-12V;
3 with the sensor sensitivity adjustment potentiometer;
Directly control high current loads, the maximum load of the relay: 220V 10A or 30V 10A (less than this requirement can be used)
Delay time: by the microcontroller programming, any set
5.PCB Size: 56mm * 28mm * 18mm length X width X height
This module through the serial port board download.
【Functions】
1 soil water shortage, the relay immediately suck, watering the soil. Until no longer water shortage is detected, the relay was disconnected.
2 soil water shortage, the relay immediately suck, watering the soil. Set a watering time (such as experience 10s), and then automatically disconnected.
3 soil water, the relay immediately suction and soil water shortage, the relay immediately disconnect
Directly through the microcontroller relay control, relay the next day, for example, and delay 20s automatically disconnect, watering the flowers this way (The advantage of this model is: do not need soil probe, control time to prepare, convenient)
[Module wiring instructions ]
1 standard 4P black RX TX GND +5 V pin module STC microcontroller program download interface (SCM Model: STC15F104E) If the user does not modify the module program, do not pick the four interfaces.
2 standard 3P black VCC GND +5 V pin module power supply interface, where buyers want to pay special attention to, and must not pick the wrong line. Below detailed description:
If your external supply voltage of 5V, connected to +5 V and GND (+5 V positive, GND negative)
If your external supply voltage of 9-12V, then VCC and GND (VCC, GND negative)
3 2P bent pin for soil probe interface, polarity and direction.
4 relay outputs normally open normally closed public relay pull is normally open and public pull normally closed disconnect with the public; relay disconnect is normally open disconnect with the public, normally closed with public pull, users can be based on this principle to control its own circuit.
【module is not applicable ]
1 does not apply to accurate soil moisture measuring instrument, such as buyers want to measure a soil humidity (humidity 68% ), that this function can not achieve this module is mainly used for the testing of the switch, such as to set a threshold value, then the soil moisture is less than or more than this value, this module can sense out of.
