Wireless Temperature & Humidity Sensor

$31.95 Solde

This wireless coin cell battery-operated Temperature and Humidity sensor is one of the finest & highest-accuracy devices you can get. It has a Sensiron sensor with an excellent ±2% relative humidity and ±0.3°C accuracy for most uses (see the graphs below). Sensiron, based in Switzerland, produces some of the world's most trusted environments, commonly found in the medical, industrial, and automotive sectors, as well as analytical instruments, consumer goods, and HVAC products.

The radio transmitter is our high-performance RF transceiver that transmits temperature and humidity to a receiver (IoT Gateway, WiFi Gateway, or Flex RF Module) using 128-bit AES encryption.

The sensor and transceiver are capable of operating over a wide voltage range (2-3.6V), making them 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).

 

 

Technical Specs:

  • ±2% relative humidity and ±0.3°C accuracy
  • High-performance RF transceiver based on the market-leading CC1100 SOC.
  • A wide operating voltage range of 2-3.6V makes the devices well-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.
  • Driverless installation.
  • All the devices are highly configurable through the serial port or over the air using the LLAP messaging protocol specified in the manual. 
  • The base station communicates via a serial port (TTL UART).
  • Communicates in clear ASCII 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.
  • A virtually unlimited number of devices can be deployed—99,999 Personal Area Network IID's, 10 channels per frequency, and 7,744 Device IID's per network.
  • Super low power consumption allows devices to be used with a coin cell battery for long periods of time (up to 1/2 year depending on transmission rates).
  • Supports six 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).
  • A battery monitor to keep track of power consumption. 

Serial Specification:

  • UART Serial (Tx, Rx, VCC, GND)
  • 3V
  • 9600 baud, N, 8, 1
  • Clear text 12-character LLAP message protocol format (more details here)
