• Deneyap Smoke Detector detects flammable gases (LPG, Propane, Butane, Methane, Alcohol, Hydrogen, Carbon Monoxide, Smoke) in the range of 100-10,000 ppm.
• It features Winsen MQ-2 timer and ST Microelectronics STM8S003F3 microprocessor.
• You can receive data from the analog input and digital 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.
• Breadboard compatible; However, the sensor legs must be shortened in order to attach it to the breadboard.
• 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.
