P45 Vertical Mount Water Level Sensor Float Switch – PP Plastic Liquid Level Control for Arduino & IoT

Overview

The P45 Vertical Float Switch is a compact, cost-effective solution for liquid level sensing. Constructed from high-quality Polypropylene (PP), it is resistant to corrosion and suitable for water, light oils, and non-corrosive chemicals. Its vertical design allows it to be mounted at the top or bottom of a tank. Because it uses a hermetically sealed magnetic reed switch, it is incredibly durable and can withstand millions of cycles without wearing out.

Key Features

• Dual Mode (NO/NC): By simply removing the small C-clip and flipping the float upside down, you can switch the module from Normally Open (turns on when water rises) to Normally Closed (turns off when water rises).

• Compact Mounting: Small enough to fit in pet bowls, hydroponic reservoirs, or small aquariums.

• Mercury-Free: Safe for environmental and food-related projects.

• Low Power Requirement: Ideal for signal-level switching for microcontrollers like Arduino, ESP32, and Raspberry Pi.

• Robust Seal: The reed switch is encased in the stem, protecting it from moisture and oxidation.
