Grove - 2-channel inductive sensor / switch
Description:
The Grove - 2-channel inductive sensor is based on Texas Instruments(TI) LDC1612, a 28-bit inductance-to-digital converter for inductive sensor solutions. The sensor detects the proximity of conductors, especially metal, by measuring inductance.
The LDC1612 measures the parameters of the LC oscillator to determine the amount of energy required to maintain the LC oscillation. This makes it possible to determine the distance between the object and the LC oscillator.
Features:
- Excellent detection range (>20 cm)
- Supports 2 channels with tuned sensor drive
- Powerful interference suppression and durability
- Multiple reference clocking options
- Low power consumption (35 µA power saving mode)
- Grove unified socket for versatile use
Application:
- Buttons in consumer products, home appliances and automobiles
- Linear and rotary encoders
- Buttons in home electronics, wearables, manufacturing and automotive applications
- Keyboards in manufacturing and appliances
- Slide buttons in consumer goods
- Metal detection in industry and automotive
- POS and EPOS
- Flow meters in consumers and appliances

What is Grove?
Grove facilitates connection, experimentation and simplifies the prototyping process. No jumpers or soldering are required. More than 300 Grove modules have been developed to cover a wide range of applications and fulfill a variety of requirements. Not only the hardware is open source, but also the software. We offer various Grove Shields to enable a connection to the Grove system with various microcontrollers.
