Exactly as described
0-5V output maps nicely to my Arduino ADC with a simple voltage divider. Fast response.
5 FAQ
Q: Does it come with a calibration certificate?
A: No, but the unit is factory calibrated before shipping.
Q: Is it suitable for outdoor use?
A: It is IP54 rated, so it is suitable for protected outdoor areas but not direct exposure to heavy rain.
Q: Can this connect directly to a 3.3V microcontroller?
A: No, the output is 0-5V. You should use a voltage divider to step it down for 3.3V logic.
Q: Can I submerge this sensor in water?
A: No, it is not waterproof for submersion. It is only splash resistant.
Q: What is the power consumption?
A: Typically less than 50mA at 24V DC supply.
