Description

MQ-4 Gas Sensor Module detects the presence of methane (CNG) gas at concentrations from 300 ppm to 10,000 ppm, a range suitable for detecting gas leaks. The sensor’s simple analog voltage interface requires only one analog input pin from your microcontroller.

Specifications :

  • Power requirements : VCC – 5V±0.1
  • DO output : TTL digital 0 and 1 (0.1 and 5V)
  • AO output : 0.1-0 .3 V (relative to pollution), the maximum concentration of a voltage of about 4V
  • Detection Gas : Natural gas/Methane
  • Detection Concentration : 200-10000ppm (Natural gas / Methane)
  • Interface: 1 TTL compatible input (HSW), 1 TTL compatible output (ALR)
  • Heater consumption: less than 750mw
  • Operating temperature: 14 to 122 °F (-10 to 50°C)

    HM-10 Bluetooth 4.0

    $6.00

    Module is used where short distance wireless communication is needed. The module is used for wireless communications of less than 100 meters. The module is preferred where power consumption is issue. HM-10 MODULE is designed by BLE chip so it consumes very less power to function. So the module can be used on mobile systems. The module uses UART communication and so it can be interfaced with almost all controllers or processors.

    Arduino Pro Mini 8MHz

    $5.50

    Arduino Pro Mini is minimal design approach to Arduino. This is a 3.3V and 5V Arduino running the 8MHz bootloader. Arduino Pro Mini does not come with connectors populated so that you can solder in any connector or wire with any orientation you need. We recommend first time Arduino users start with the Uno R3. It’s a great board that will get you up and running quickly. The Arduino Pro series is meant for users that understand the limitations of system voltage (3.3V) and (5V), lack of connectors, and USB off board.
