Frequently Asked Questions

What is the operating voltage range for the HS-S33P sensor?

The HS-S33P sensor is designed to operate at a dual voltage of either 3.3V or 5V DC. Ensure your microcontroller or power supply provides a stable voltage within this range. The sensor draws a maximum working current of 20 mA.

How do I connect the HS-S33P to my Arduino or Raspberry Pi?

Connect the sensor using the PH2.0 3-pin connector. The pinout is: VCC (V) to 3.3V/5V, GND (G) to ground, and Signal (S) to a digital input pin on your microcontroller. No analog pin or ADC is required as the output is digital.

Is this sensor suitable for permanent outdoor installation?

The HS-S33P is constructed primarily from PCB material and is best suited for controlled environments, greenhouses, or potted plants. For permanent, harsh outdoor installation, consider sensors with corrosion-resistant probes and higher IP ratings for water and dust protection.

What does the digital output signal indicate?

The digital output pin provides a logic-high or logic-low signal based on a preset moisture threshold. The output toggles when the detected soil moisture crosses this internal level, allowing for simple on/off control in automated watering systems.
