Product Description

RAK12029 is a metal detection sensor module based on the LDC1614 from Texas Instruments. The LDC1614 is an inductance-to-digital converter (LDC) that measures the oscillation frequency of four LC resonators. It outputs a digital value, that is, proportional to frequency, with 28 bits of measurement resolution. With this digital value, you can detect the presence of metallic objects.

Product Features

• Metal detection module
• Sensing coils up to four channels
• 28-bit LDC
• Immunity to DC magnetic fields and magnets
• 3.3 V Power supply
• Operating Current: 0.2 uA to 2.1 mA
• Chipset: Texas Instruments LDC1614
• Module size: 25 x 35 mm

Prerequisites

To use a RAK12029, you need at least a WisBlock Base to plug the module in. The WisBlock Base should have a connected battery to provide power supply to the RAK12029 module. Furthermore, you need a WisBlock Core module to use the sensor.

warning

Make sure to fix the module with the screws to ensure a proper function.
