Wireless Multi Sensor Mk3 (WMS Mk3)
  • Very low power consumption (6.5uA between transmissions with 1 DS18B20 sensor connected)
  • Very long range
  • Micro USB power feed
  • Screw terminals for a soldering free installation
  • Tailored to fit perfectly in plastic box (not included)
  • Improved RF Transmitter with great transmitting range
  • Professionally assembled
  • Makes 1-wire network wireless
  • CO2 sensor support (choose variant below)
  • Very compact design (29x25mm)
The WMS Mk3 is compatible with Tellstick DUO and Tellstick NET from Telldus and Rfxtrx433 from RFXcom.
The following sensors/devices are supported,
  • DS18B20
  • DS18S20
  • DS1820
  • DS18B22
  • DS2450
  • MAX31850K
  • DHT22 combined temperature and humidity sensor (a.k.a. RHT03 and AM2302).
  • Event type sensor that have 0-5V TTL logic out. As an example a PIR-sensor (HC-SR501) can be used to detect motion. Other examples can be a doorbell switch, mouse trap, door switch, you name it.
  • Carbon dioxide (CO2) sensor S8 from SenseAir and MH-Z19 (eBay)(aliexpress) More info here.
A more extensive list of supported devices can be found here.
For every sensor of any type of the above, there will be a Temperature-Humidity sensor visible on the Tellstick DUO/NET or RFXtrx433 side.
As an example. Lets say that you have 1 WMS Mk3 to which you have connected a 1-wire network with 5 DS18X20 temperature sensors, and 1  DHT22 sensor, and 1  PIR-sensor (HC-SR501). Then this will be seen on the receiving side as 7 separate sensors in total where the 7th sensor will show upp only if a movement has been detected (signal transition from 0V -> 5V).

You will get:
1 pcs Wireless Multi sensor Mk3 fully assembled with the latest firmware

I recommend the box from Hammond 1551. The box comes in black or white, with or without flanges. Note that the CO2 sensor S8 will not fit inside the box.
