The RFP-602 is a flexible, ultra-thin piezoresistive pressure sensor designed to detect and measure pressure, force, and weight. It works by changing its resistance in response to applied force—when pressure increases, its resistance decreases. This makes it useful in applications requiring touch, force, or pressure sensing. The sensor is highly flexible, lightweight, and easy to integrate into various surfaces and systems.

It is commonly used in robotics, medical devices, electronic scales, industrial automation, and interactive touch interfaces. Its flexible and ultra-thin design allows it to be placed on curved or irregular surfaces without affecting performance.

A soil moisture sensor is an essential tool used in agricultural, gardening, and environmental monitoring systems. It is used to detect the amount of moisture in the soil, ensuring that plants receive the right amount of water for optimal growth. The corrosion-resistant probe enhances the sensor's durability, making it ideal for long-term use in outdoor and harsh environments.
