Our sensors are easy to deploy, with a range of mounting options and user replaceable batteries offering wire-free installation.They are powered by one half 3,6V AA lithium battery . The Battery life is estimated to be up to 10 years but depends on sample interval, transmit interval, data rate, power output and environmental factors. All our Elsys sensors are equipped with NFC for easy configuration with an Android phone.
