General Purpose Pod
The A1-01a General Purpose Sensor Pod is designed for general environmental measurements. It provides several different internal sensors, as well as a screw terminal connector for connecting to a wide range of external analog sensors. The pod also includes a +5Vdc output to power external sensors.
In the event no gateway can be reached, individual pods will store up to 255 data points, until a connection is restored. Pods have a range of approx. 80m (250ft), and can also act as a repeater for other's signals.
Package Includes
- A1-01 Pod
- Pin-out Guide
- AC Adapter
- Standard Antenna
- Wall Mounting Bracket
- Batteries (3xAA)
