DENEYAP Capacitive Soil Moisture (M38)
  • Thanks to its special design, Deneyap Soil Moisture Meter is easily inserted into the soil and measures capacitively. It is resistant to corrosion.
  • It features a Texas Instruments TLC555QDR timer and ST Microelectronics STM8S003F3 microprocessor.
  • You can receive data from the analog input pins of your development card by using the module's pins other than the I2C communication interface.
  • The module has 2 I2C communication connectors (JST SH 4 pin 1 mm).
  • You can connect the modules to each other easily and quickly in a chain arrangement.
  • You can use it compatible with all Deneyap development cards.
  • It is breadboard compatible.
  • Arduino Uno, Raspberry Pi Pico, etc. without I2C communication connector. You can connect development cards to each other via their pins.
  • It is suitable for coding with Arduino IDE.
  • Electronic modules and development boards with Adafruit Stemma QT and Sparkfun Qwiic communication connectors can work together.
