Overview​

Figure 2630: RAK12023 WisBlock Soil Moisture Sensor Connector

Description​

RAK12023 is a soil moisture connector module. It has one (1) standard WisBlock IO connector, which you can connect with the WisBlock Base. It also has three (3) connectors dedicated to the RAK12035. RAK12035 is a separate soil moisture sensor probe that can be connected to the RAK12023 module. RAK12023 is capable of a connection of up to three RAK12035 soil moisture sensor probes simultaneously.

Features​

  • A Separate sensor PCB module RAK12035 is required.
  • Three (3) available connectors for the soil sensor PCB module RAK12035.
  • Module size: 15 x 25 mm

Specifications​

Overview​

Mounting​

The RAK12023 WisBlock Soil Sensor Connector Module can be mounted to the IO slot of the WisBlock Base board. Figure 2 shows the mounting mechanism of the RAK12023 on a WisBlock Base module.

Hardware​

The hardware specification is categorized into three (3) parts. It discusses the pinouts and their corresponding functions and diagrams of the module. Also, it shows the mechanical characteristics of the RAK12023 WisBlock Soil Moisture Sensor Connector Module.

Pin Definition​

The RAK12023 WisBlock Soil Sensor Module comprises a standard WisBlock connector. The WisBlock connector allows the RAK12023 module to be mounted to a WisBlock Base board. The pin order of the connector and the pinout definition is shown in Figure 3.

NOTE
  • Only I2C related pin, IO4, 3V3_S, and GND are connected to the WisConnector.
  • 3V3_S voltage output from the WisBlock Base that powers the RAK12023 module can be controlled by the WisBlock Core via WB_IO2 (WisBlock IO2 pin). This makes the module ideal for low-power IoT projects since the WisBlock Core can totally disconnect the power of the RAK12023 module.
