Wireless Pressure, Temperature & Humidity Sensor

Regular price $0.00 $34.95 Sale

3 in 1 wireless environment sensor with Pressure, Temperature and Humidity. It is low cost and super accurate : +-3% humidity, +-1hPa and 1C. This sensor can also be used to determine altitude with a high degree of accuracy (+-1M) thanks to the accuracy of the pressure sensor. 

The radio transmitter is our high-performance RF transceiver that transmits the sensor readings to a receiver (IoT Gateway or Flex RF Module) over 128bit AES encryption.

The sensor and transceiver are capable of working  over a wide operating voltage (2-3.6V) making it suitable for battery power. Based on our calculations the sensor should last 6 months on a single CR2032 coin cell battery with 5 minute transmission intervals (being confirmed through testing). 

Size: 51*36*20mm

Technical Specs:

  • ±2% relative humidity and ±0.3°C accuracy
  • High-performance RF transceiver based on the market-leading CC1100 SOC.
  • Wide operating voltage range of 2-3.6V makes the devices suited for battery power.
  • Current consumption: RX: 16.2 mA , TX: 15.2 mA. Deep Sleep : 0.005Ma (0.5 µA).
  • Up to 1KM line of sight. Short range (~30M) penetration of walls and floors.
  • 128-bit AES encryption security.
  • Driver-less installation.
  • All the devices are highly configurable through the serial port or over the air using the LLAP messaging protocol specified in the manual. 
  • Base station communicates through serial port (TTL UART).
  • Communicates in ASCII clear text making it very easy to exchange data between devices over the air.
  • Supports point to point, point to multi-point, multi-point to point and multi-point to multi-point.
  • Virtually unlimited amount of devices can be deployed. 99,999 Personal Area Network ID’s, 10 channels per frequency and 7,744 Device ID’s per network.
  • Super low power consumption allows devices to be use with a coin cell battery for long periods of time (up to 1/2 year depending on transmission rates).
  • Supports 6 frequencies (433 MHZ, 915 MHZ (US & Canada), 868.3 MHZ (Europe), 868 MHZ, 903 MHZ, 315 MHZ)
  • 10 channels per frequency.
  • Serial communication with external micro-controllers like Raspberry Pi and Arduino (Tx, Rx, GND, 3V3).
  • Battery monitor to keep track of power consumption. 

Serial Specification:

  • UART Serial (Tx,Rx, VCC, GND)
  • 3V
  • 9600 baud , N, 8, 1
