SenSpot™ Humidity/Temperature uses Resensys's proprietary Active RF Technology, similar to other SenSpot™ in its family. Resensys ART technology offers a high performance method for large-scale sensing, wireless synchronization, and ultra-energy efficient wireless communication. SenSpot™ is designed to operate maintenance-free for decades. SenSpot can operate for at least 10 years without battery replacement. Due to small size and lightweight design, the adhesive-mount SenSpot™ can be applied easily to as many critical spots on a structure as needed, with minimal installation effort. SenSpot™ Humidity/Temperature has a measurement probe which can easily extend the data point to even inside and inaccessible area of a structure. The probes can be customized to be up to 200 feet long.

SenSpot - Wireless Transmitter Wireless transmitter is universal and it reads the analog measurement from the sensing element and transmits the digitized data wirelessly to SeniMax. These units come in either self-adhesive or flange-mount form factors.
