AD-Node: Accurate analogue and digital measurements with LoRaWAN connectivity

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 Thermistors, two 0–1.5V Analogue inputs 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.

The AD-NODE is ideally suited to the following applications, and sensors:

• Dendrometry, supporting up to 2 x DBV60 Band Dendrometers.
• Soil Moisture, supporting 1 x MP406
• Microclimate, supporting the ATH-2A for accurate air temperature and relative humidity
• Water level, supporting the ECL 8439 Submersible Pressure Transmitter

MFR-NODE: IoT Node for use with SDI-12 and analogue inputs

The MFR-NODE supports sensors with higher power requirements; a solar panel can charge either the internal lithium-ion battery or both the node and sensor can be powered by an external DC power system (e.g. battery or mains source). With an onboard SD-Card, the MFR-NODE provides stand-alone data logging capabilities and full data redundancy in the event of temporary loss of communications or dropped packets – ideal for research applications. Data is stored in csv format for ease of use.

The MFR-NODE has been designed to provide flexible communication, sensor and power options. The MFR-NODE supports SDI-12, four 32-bit dry-contact counting digital inputs and four single-ended (two differential) 0 – 3 V analogue inputs, with selectable 12 V, 5 V or 2.5 V excitation and a 0-100khz frequency input.
