Product Description

Tank Pool Horizontal Water Level Float Switch Sensor

= Liquid Level Sensor with PP Plastic Ball for Arduino =

This horizontal float switch provides accurate liquid level detection for tanks, pools, and reservoirs. Its PP plastic construction ensures durability and corrosion resistance for water-based applications.

Simple ON/OFF Output - Digital signal for easy Arduino integration
Durable PP Material Corrosionresistant for long-term use
Operates as a reed switch - treat as a sensor, not a power switch
Use 10kΩ pull-down resistor for stable Arduino readings
Max switching current is 0.5A - use a relay for loads

√ 2-wire connection for easy wiring

√ Corrosion-resistant PP construction

√ Works with Arduino, ESP32, Raspberry Pi

= Connection Guide =

Wiring to Arduino:

  • One wire: Connect to 5V or 3.3V
  • Other wire: Connect to digital input pin
  • Add 10kΩ pull-down resistor to ground

Reading the sensor:

  • Use digitalRead(pin) to get state
  • HIGH = float up (or down, depending on orientation)
  • LOW = float down (or up)
Mount sensor at desired trigger level
Flip sensor orientation to change NO/NC behavior
Do not exceed 0.5A through the switch
Use a relay for pumps or high-current loads

= Wiring Tips =

Always treat this as a low-current signal device. For controlling pumps or other loads, use the sensor to trigger a microcontroller, which then activates a relay or MOSFET. This protects the reed switch from damage.

Simple Interface - Just two wires and a resistor

Safe Operation Lowcurrent sensing protects the switch

Used in hydroponics and aquariums
Reliable and cost-effective

√ 10W contact rating for control signals

√ PP body resists water damage

= Troubleshooting =

Sensor not triggering:

  • Check orientation - float may need to be up or down
  • Verify pull-down resistor connection
  • Avoid loose wiring

Erratic readings:

  • Ensure sensor is securely mounted
  • Check for debris blocking float movement
  • Use software debounce in Arduino code
