LDC1000EVM

The LDC1000EV is an evaluation board that is used to measure the capacitive sensor that measures relative permittivity and ac inductive sensing. It is designed with a variety of application fields, allowing for easy integration and operation in various operations. This article aims at explaining the application fields and working principle of the LDC1000EV.

Application Fields

The LDC1000EV is designed with an array of application fields. For example, the board has been used in automotive for proximity sensing, such as in door, bonnet and boot open detection. It can also be used in power tools and white goods for drag detecting, along with being used for mechanical and rotating parts for safety actuation. It can also be used in medical fields for emerging control and access, along with low power applications as it consumes 0.5mW of power. Other application fields for the board are consumer electronics, industrial electronics, medical engineering, and automotive sensors.

Working Principle

LDC1000EV is based on a capacitive sensing technology. The board consists of two coils, placed on separate surfaces, to form a capacitive voltage divider. The board is fitted with a high-resolution capacitance to frequency converter as well as two range selectable switches that can be used to hide or display the board, as needed. When a signal is sent to the sensing element, the energy is measured within the two coils to capture the relative permittivity. This signal is amplified and forwarded to external hardware for further analysis. The amplified signal is a sinusoidal waveform that is modulated by the signal that has been received. The other output signal is in the form of an electrical circuit connected to the measuring coil, used to measure the external voltage and temperature.

Conclusion

LDC1000EV is an effective evaluation board that can be used in a range of applications. Its capacitive sensing technology and two coils provide a system for easy integration and operation in nearly any environment. The board has a range of uses, including automotive, white goods and medical fields. Additionally, the board has built-in features for easily measuring external voltage and temperature, along with enjoying a low power consumption of 0.5mW.
