Soil Moisture Sensor Kit (Soil Moisture Sensor Kit)

Product description

This is a must have tool for a connected garden! It will be helpful to remind you to water your indoor plants or to monitor the soil moisture in your garden. Through adjusting the potentiometer to control the soil humidity threshold,can automatic watering the vegetable garden, garden, control the flower pot soil moisture. Particularly suitable for people who travel frequently!

Usage
Test relay module: connect the relay module VCC to 5V, GND to ground, IN to GND, the relay will jump, and when IN is suspended, the relay will resume, so repeatedly, you can hear the relay "Kaka" sound.
Test the soil moisture sensor module: Connect the fork probe and transmitter module with two DuPont wires. The transmitter module VCC is connected to 5V, GND is grounded. When the power is on, the red power light is always on, and the green (blue) light is flashing once. The fork probe is used. Directly inserted into the water, the green (blue) color indicator light is on. The red line of the water pump is connected to 5V, the black line is grounded, the pump works, pay attention to the test for 1 second, and it is not allowed to work in the air for a long time. Connect the system, powere on and if the pump has been working, it is correct. Because in the air, the probe can not detect the humidity, there is no problem if it is installed correctly in the pot.

IR Infrared Transmitter Sensor Module
This Infrared Obstacle Avoidance Sensor Module is an inexpensive solution to avoidance detection for robotics and other electronics uses. It comes as an assembled module, as shown above, there are only four pins: 5-volts, GND, output, and EN. Output is an active LOW and has an onboard status LED. It’s very easy to interface directly with micro-controllers. It also works with the Raspberry Pi with a voltage range of 3-6 volts. Connect Vcc to 3-volts.
The enable pin “EN” will disable the device when HI (Vcc) and enable when LO (GND). The onboard jumper can be left open to allow external control of enable/disable of the module. There are two potentiometers on the module one controlling operating frequency (centred at 38 kHz) the other controlling intensity. The detector was designed for 38 kHz and the onboard oscillator circuit is based on a 555 timer.

MPR121 Breakout V12 Capacitive Touch Sensor Controller Module I2C keyboard (MPR121)
Model NumberMPR121
ChannelsN/A
Input Voltage2.5 to 3.6 V DC
Response TimeN/A
InterfaceI2C
ColorBLACk
Operating Temperature-20 to 70 deg C
MaterialAlloy Plastic

Description : This MPR121 is a capacitive touch sensor controller driven by an I2C interface. The chip can control up to twelve individual electrodes, as well as a simulated thirteenth electrode The MPR121 also features eight LED driving pins, when these pins are not configured as electrodes, they may be used to drive LEDs. There are four jumpers on the bottom of the board, all of which are set (closed) by default. An address jumper ties the ADD pin to the ground, meaning the default I2C address of the chip will be 0x5A. If you need to change the address of the chip (by shorting ADD to a different pin), make sure you open the jumper first. Jumpers also connect SDA, SCL, and the interrupt pin to 10k pull-up resistors. If you do not require the pull-up resistors you can open the jumpers by cutting the trace connecting them.

Features of MPR121 Breakout V12 Capacitive Touch Sensor Controller Module:
  1. Capacitive touch sensor controller driven by an I2C interface.
  2. Can control up to twelve individual electrodes, as well as a simulated thirteenth electrode.
