• Deneyap Rain Sensor produces logical values according to the amount of water or water vapor.
• It consists of two circuits; These circuits are connected to each other with a 2 pin female-female connection cable (jumper). One of the circuits has a resistive surface and is placed in the area to be detected.
• It houses the ST Microelectronics LM393DT comparator and the ST Microelectronics STM8S003F3 microprocessor.
• Apart from the I2C communication interface, you can receive data using the digital or analog inputs of your development card by using the pins of the module.
• 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.
