Hi, in this instructable we’ll make wireless sensor network modules (transmitter & receiver) and we’ll be monitoring 7 different MQ series gas sensors’ output (MQ-2, MQ-3, MQ-5, MQ-6, MQ-7, MQ-8 and MQ-135) from our PC. We’ll be using Arduino Nano and nRF24L01 modules on both the transmitter and the receiver modules.

Arduino Nano (or other model) 2 , nRF24L01 tranceiver module 2, 100microFarad capacitor *2, jumper cables, 5V power supply (2 usb output power bank is used in this project), circuit board (optional, all can be done on breadboards as well), MQ series gas sensors.”
