A turnkey solution of Wireless temperature&humidity monitoring

AppconWireless has delivered a type of low-cost and easy-implementation environment monitoring solution designed for operation in the unlicensed ISM and LPRD bands at 433MHz. GFSK modulation/demodulation, multi-channel operation, high bandwidth efficiency and anti-blocking performance make the solution easy to realize the robust and reliable wireless link in the harsh environment.

The module integrates 12bit high resolution ADC which can be used to connect different types of analog or digital sensors such as PT1000, DS18B20, SHT21/25, etc. Users don’t need to program for the sensor and module, as to no external MCU or other components needed for the monitoring nodes. The sensors can be soldered on the transmitting module directly to build a wireless sensor network, which minimizes the solution cost and reduces development period for new projects.

RF4432S is RF Sensor Receiver Module. The RF4432S is a low-cost sub-1GHz receiver based on si4432 RFIC. It can only be used as receiver in wireless sensor application to receive the data from the APC300.

RF5151 is a type of low-power consumption(10mW) transmitter module designed for operation in the licensed-free ISM band. The module integrates 12bit high resolution ADC which can be used to conjunction different types of analog or digital sensors DIRECTLY. The sensors is PT1000, DS18B20 and SHT21/25.Users don't need to write codes between sensor and RF5151 WITHOUT external MCU or other components.The module can be run by the battery power and has the function to monitor the battery voltage.
