Product Details:

Model NumberTTP223B
Channels1
Input Voltage2.0 to 5.5 V DC
Response Time60 ms
ColorBlue
Operating Temperature-40 to +85 deg C
Dimensions24 x 24 x 7.2 mm

The module is based on a touch-sensing IC (TTP223B) capacitive touch switch module. In the normal state, the module output low, low power consumption. When a finger touches the corresponding position, the module output high, if not touched for 12 seconds, switch to low-power mode.

Technical Details :
  • Low power consumption
  • Can replace the traditional touch of a button
  • Four M2 screws positioning holes for easy installation
  • Output pin pull-up current: 4mA
  • Response time (Low Power mode): 220mS
  • Response time: 60mS

    Model NumberFC-28
    TypeCapacitive
    Usage/ApplicationGarden Plants
    Operating Voltage3.3 to 5.5 V DC
    Output Voltage0 to 3.0 V DC
    Operating Current15 mA
    InterfaceRS485
    Soil Probe Dimension6 cm x 3 cm
    PCP Dimensions3 cm x 1.5 cm
    Country of OriginMade in India

    Instructions for Use:
    • Soil moisture module is most sensitive to the ambient humidity is generally used to detect the moisture content of the soil
    • Module to reach the threshold value is set in the soil moisture, DO port output high, when the soil humidity exceeds a set threshold value, the module D0 output low
    • The digital output D0 can be connected directly with the microcontroller to detect high and low by the microcontroller to detect soil moisture
    • The digital outputs DO shop relay module can directly drive the buzzer module, which can form a soil moisture alarm equipment
    • Analog output AO and AD module connected through the AD converter, you can get more precise values of soil moisture

    ModelLM393
    TypeLDR Sensor Module
    Power Frequency50 Hz
    Operating Voltage3.3 to 5 V DC
    PCB size3 x 1.6 cm

    Features:
    Can detect ambient brightness and light intensityAdjustable sensitivity (via blue digital potentiometer adjustment)Operating voltage 3.3V-5VOutput TypeAnalog voltage output -A0Digital switching outputs (0 and 1) -D0With fixed bolt hole for easy installationSmall board PCB size: 3cm * 1.6cmPower indicator (red) and the digital switch output indicator (green)Using LM393 comparator chip, stablePin outs:
    External 3.3V-5V VCCExternal GND GNDDO digital output interface, a small plate (0 and 1)AO small board analog output interfaceHow to use:
    Photosensitive resistor module most sensitive to environmental light intensity is generally used to detect the ambient brightness and light intensity.Module light conditions or light intensity reach the set threshold, DO port output high, when the external ambient light intensity exceeds a set threshold, the module D0 output low;Digital output D0 directly connected to the MCU, and detect high or low TTL, thereby detecting ambient light intensity changes;Digital output module DO  can directly drive the relay module, which can be composed of a photoelectric switch;Analog output module AO and AD modules can be connected through the AD converter, you can get a more accurate light intensity value
