The most important hardware in IoT might be its sensors. These devices consist of energy modules, power management modules, RF modules, and sensing modules. RF modules manage communications through their signal processing, WiFi, ZigBee, Bluetooth, radio transceiver, duplexer, and BAW.
The sensing module manages sensing through assorted active and passive measurement devices. Here is a list of some of the measurement devices used in IoT:
Devices accelerometers temperature sensors magnetometers proximity sensors gyroscopes image sensors acoustic sensors light sensors pressure sensors gas RFID sensors humidity sensors micro flow sensors
