Scigiene’s Wireless Gen 2 Temperature/Humidity Sensor with probe allows you to monitor the relative humidity of the air within a room or enclosure. It is ideal for monitoring humidity within greenhouses, industrial spaces, museums, saunas and humidors. They can also be used for residential applications such as controlling mold, mildew or dust mites.  Scigiene's wireless sensors are ideal for pharmaceutical, medical and other high tech applications where loss of data is unacceptable.  These also have an amazing range of over 1000 ft. with 10 year battery life and can be remotely upgraded via network connections.  These are truly the most advanced wireless sensors available.    


  • Wireless range of 1,200+ feet through 12+ walls
  • Frequency-Hopping Spread Spectrum (FHSS)
  • Best-in-class interference immunity
  • Best-in-class power management for longer battery life
  • Encrypt-RF® Security (Diffie-Hellman Key Exchange + AES-128 CBC for sensor data messages)
  • Datalogs 2000 to 4000 readings if the gateway connection is lost (non-volatile flash, persists through the power cycle): 10-minute heartbeats = ~ 22 days, 2-hour heartbeats = ~ 266 days
  • Over-the-air updates (future-proof)

1. Refer to the humidity/temperature graphics below for more detailed information on the sensors accuracy and range.

2. Response time (T of 99.3%) is significantly affected by air flow and the conditions present in the immediate vicinity of the sensing element.

3. High temperature limited by heat shrink at 70°C. The sensor electronics in the lead are rated to 125°C and will not fail at 70°C but the heat shrink and heat shrink adhesive may become malleable at this temperature compromising the waterproof seal.

4. Operating and storage altitude without DC power supply is -30.48 to 9144 m (-100 to 30,000 ft).
