Easy to install
I am not an expert in electronics, but the color-coded wires made connection simple. The enclosure keeps the sensor safe from dust in my workshop.

Good value, accurate readings
Compared it against a professional hygrometer and the readings were within 2%. The plastic case feels durable enough for indoor use. Would prefer soldered terminals instead of loose wires though.

Exactly what I needed
The IP65 rating gives me confidence using this near my irrigation system. It handles the humidity spikes well without drifting. Highly recommend for gardening automation.

Reliable industrial sensor
We deployed ten of these in our warehouse monitoring system. They have been running stable for three months now. The voltage output is linear and easy to calibrate in software.

Solid performance
Response time is decent for general monitoring. Not suitable for rapid fluctuation detection, but perfect for logging ambient conditions over time. Good build quality.

Perfect for my greenhouse project
The enclosure is sturdy and the wires are long enough to reach my controller easily. The 0-5V output integrates perfectly with my Arduino setup without needing extra converters.
Q: Can this module be used directly with a 3.3V microcontroller?
A: The module requires a 5V power supply to operate correctly. While the output is 0-5V, you may need a voltage divider or an op-amp circuit if your microcontroller's ADC cannot handle 5V inputs safely.
Q: Is the enclosure waterproof for outdoor rain exposure?
A: The enclosure has an IP65 rating, which means it is dust-tight and protected against water jets from any direction. It is suitable for outdoor use under a small overhang but should not be fully submerged or exposed to high-pressure washing.
Q: Does this support digital communication like I2C or UART?
A: No, the WHTM-03 model specifically provides an analog 0-5V voltage output only. If you require digital protocols like I2C or UART, please check our WHTM-Digital series products.
Q: How often does the sensor need calibration?
A: The sensor comes factory-calibrated. For most applications, annual verification is sufficient. If used in extreme environments with constant high humidity or contaminants, more frequent checks may be beneficial.
Q: What is the pinout configuration for the loose wires?
A: The four wires are color-coded: Red is VCC (5V), Black is GND, Yellow is the Analog Output (0-5V), and Blue is NC (Not Connected). Please refer to the datasheet included in the package for verification.
