Communicating with your data logger has never been easier. The Em50G Solar gives you unorecidented battery life as it lets you check in on your data logger from virtually anywhere in the world. The Em50G Solar is a self-contained data logger built to power, read, and log data from five sensors. Logged data are transmitted from the logger to Decagon's server via internal cellular/mobile communication. All Decagon sensors work with the Em50G Solar; no programming is necessary.
