Description

General Purpose Pod

The Accsense A1-01a wireless environmental data logger 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 data until a connection is restored. The stored data will be transferred to the online account. 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)

Internal sensors:

  • Ambient Temperature
  • Vibration
  • Humidity
  • Acoustic Level
  • Ambient Light

External Sensor Inputs:

  • 4-20mA Current Input with +20Vdc Loop
  • Digital Input (Contact Closure)
  • Counter
  • 0-5Vdc Analog Input with +5Vdc Sensor Drive
