PDF datasheet and reference files.

 Description. The Angel-TEM is a simple, rugged, compact module that continuously monitors and records environmental safety data. Specifically, it senses audio noise level, barometric pressure, humidity, shock, and temperature.  It may be used to protect humans, non-human animals, and material assets. Its rechargeable battery allows for 30 day operation under most use cases. It has a programmable audio alarm. It has 256 kB data storage. It has a USB-C (cable included) port for data access and recharging. It has a secure wireless interface for remote operation. It is small enough to fit easily inside a hard hat, helmet, web gear, or other means of securing.
