Bill of Materials: This package includes 16 pieces which are listed below along with their labels and quantity. Quantity Component Label Value / Type / Label R1, R2 1KΩ / (Brown, Black, Black, Brown) 120Ω / (Brown, Red, Black, Black) Resistors 5.1Ω... - Page 4 Assembly: 1) In order to assemble the module, you need the following tools: *It is recommended to have some isopropyl alcohol and a fine soldering brush handy to clean off the excess flux on the circuit board when the soldering is done.
- Page 5 b) The soldering iron temperature depends on the type of solder used. If you are using a typical 60/40 lead solder, depending on the thickness the temperature should be set anywhere between 370 to 500 °F (187 to 260 °C). If you are using a lead-free solder, increase above temperatures by 40 to 70 °F (5 to 20 °C).
- Page 6 You may proceed to solder the resistors in place by following the labels on the board and placing the correct color resistor indicated in the “Bill of Materials” section on page 3. All soldering will be done on the backside of the board. Insert the 8 pin (DIP8) IC socket as shown in the photo.
- Page 7 Insert the switch, DC connector and the MQ3 sensor as shown in the picture and solder them. Insert the 5mm LEDs as shown in the image. Ensure that the orientation of the LED is correct.
- Page 8 Implementation: This module should be powered up by connecting a 5V 1A DC power supply to the J1 connector. This device has an onboard high power relay rated to 24VDC 2A; therefore, you can connect any peripheral device that you desire to the output of the relay so it can be turned ON and OFF during the operation of the sensor module.
