AD-NODE: For High Resolution Analogue & Digital Sensors

The AD-NODE is designed for those requiring precision in their analogue and digital measurements. With a 24-bit ADC, the AD-NODE supports two RTDs, a 0–10V with compressing range and a 4–20mA input. Each of the four dry-contact digital inputs is capable of simultaneously sampling at 1 kHz, with periodic reporting. Settings on the device can be altered remotely via LoRaWAN™ or locally via USB.

  • LoRaWAN™ low-power long-range connectivity
  • 2x 24-bit RTD
  • 1x 24-bit Voltage input (0-10 V with compressing range)
  • 1x 24-bit 4-20 mA
  • 4x 32-bit dry-contact counting digital inputs, 2 x digital outputs
  • 400 Hz 3-Axis Accelerometer
  • 3 x AA Lithium Energizer battery
  • Fully reconfigurable via LoRaWAN™ downlinks
