WisBlock RAK12023 + RAK12035 Soil Moisture Sensor Module

This set consists of the RAK12023 connector module and the RAK12035 capacitive soil moisture sensor. The probe is inserted into the soil and measures soil moisture and soil temperature; a dedicated ATtiny441 microcontroller on the probe outputs the values via I2C. The RAK12023 has three connectors for the probe, but only one probe can be operated at a time.

WisBlock from RAK Wireless is a modular system for building custom LoRaWAN and IoT nodes. Core, sensor and IO modules are plugged onto a base board and screwed in place.

Recommended Accessories:

• WisBlock RAK19007 Base Board 2nd Gen
• WisBlock RAK19001 Dual IO Base Board
• WisBlock Core RAK4631 with LoRa/BLE 5.0

Features:

• Slot: IO slot of a WisBlock Base Board, for example RAK19007 or RAK19001 (two IO slots). The RAK19003 Mini Base Board has no IO slot
• Capacitive measurement of soil moisture, evaluated by the ATtiny441 on the probe
• Soil temperature via an NTC on the probe
• Calibration via software
• Electronics and cable of the probe are protected against moisture with heat shrink tubing
• Powered via the switchable 3.3 V line (3V3_S), can be switched off via WB_IO2

Application Examples:

• Irrigation control in gardens and greenhouses
• Monitoring of potted plants and beds via LoRaWAN
