The Vinduino R3 board contains all the electronics needed for a solar powered remote sensor platform. It is designed for optimizing agricultural irrigation, aimed at saving 25% irrigation water. This board represents the 3rd generation design of our remote sensor platform, and has gone through extensive vineyard field trials.

Features:

• Arduino based, easy to customize programming
• 4 electrically separated inputs for soil moisture sensors
• Supports Wifi (ESP8266, not included), Globalsat LM-210 LoRaLAN module for private networks (add option), the new Globalsat LM-513H module for LoRaWAN US 915 MHz public networks like TheThingsNetwork (add option)
• Irrigation valve control output
• Several options for temperature/humidity sensors
• Solar battery charger
• Real time clock for sleep mode power saving and precise irrigation timing
• Load switch for actuators or sensors that require electric power
• Passed FCC and IC regulatory testing
• Certified as open source hardware by the Open Source Hardware Association

Supported sensors:

• Watermark SS200 (calibration: http://www.irrometer.com/200ss.html)
• DHT11, DHT22
• DS18b20
• Adafruit anemometer
• HX711 load sensor module

The Vinduino board is designed for continuous unattended operation. It is designed to be powered by a small solar charged battery, keeping the system working during the night and during periods with dense cloud cover. The battery voltage can be monitored remotely to check the battery state of charge and battery health.

The board ships assembled and tested.

• The LM-210 module requires a compatible gateway, and is designed for LoRaLAN. For details please check the product manual on the Vinduino github page.

• The LM-513H module, is for US 915 MHz only, and requires a LoRaWAN gateway or an available public LoRaWAN network.
