Long-range wireless sensor modules are used in many applications, including asset tracking systems, community building security, robot wireless control, industrial remote control, telemetering, automatic data acquisition, vehicle keyless entry system, PC wireless networking, toys, and drones among others.

One such sensor is the nRF24L01 module (refer Fig. 1) from Nordic Semiconductor. For application, you may refer to ‘Ultra-Low-Power Sensor Hub Using nRF24L01 Modules’ DIY article available on this link.

Some long-range wireless sensor modules easily available in the Indian market include nRF24L01, Zigbee XBee Pro S2C 802.15.4, HC-12, TS835 FPV 5.8G, and LoRa SX1278 module.
