The SNiP-SRAD is a 'Sensor Node Integrated Package' for LoRa, LoRaWAN or FSK communication of real-time measurements of solar radiation, for continuous environmental monitoring.

The base SNiP-SRAD integrates 1x AD-NODE and 1x SP-212 Volt Pyranometer Sensor to a site's unique network, communication and power requirements.

AD-NODE: For High Resolution Analogue and 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 to 10V with compressing range and a 4 to 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.
Features

- 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

SP-212 Volt Pyranometer

The SP-212 is an amplified sensor with a 0-2.5 volt output and exhibits excellent cosine response. The SP-212 sensor can also be utilised in a custom IoT (Internet of Things). The SNiP-SRAD is a 'Sensor & Node Integrated Package' for LoRa, LoRaWAN, FSK, or GNSS (optional) communication of real-time solar radiation for continuous monitoring of plant light relations. The base SNiP-SRAD integrates 1x SP-212 Volt Pyranometer Sensor with an AD-NODE to a site's unique network, communication and power requirements.
