Product Specification
The liquid level sensing module LLM (Liquid-level Meter) measures the change of dielectric constant through the capacitance high frequency circuit. The module digital signal output liquid capacitor value, converted into liquid level height, which can measure continuous liquid level or segment level, and the module can also provide liquid temperature information for compensation. The product can be widely used in various liquid level and water immersion detection scenarios.
