Next Humidity Sensor Configuration & Installation Guide

Overview

The Next® Wi-Fi Wireless Humidity Sensor accurately monitors the air’s relative humidity (RH) within a room or enclosure. The sensor uses a high-accuracy silicon-based digital humidity/temperature element to produce % RH and temperature data. Additionally, the data is used in iMonnit to calculate dew point, moisture weight, heat index, and wet bulb temperature.

Settings to Configure

The instructions to configure standard Next Sensor and Wi-Fi network settings are available in the Next Sensor Quick Start Guide. The settings below are specific to the Next Humidity Sensor:

Below—Humidity measured below this value will cause the sensor to enter the Aware State.
Above—Humidity measured above this value will cause the sensor to enter the Aware State.
Aware State Buffer %—Prevents the sensor from bouncing between Standard Operation and Aware State when the readings are very close to a threshold.
Below (Temperature)—Temperatures measured below this value will cause the sensor to enter the Aware State.
Above (Temperature)—Temperatures measured above this value will cause the sensor to enter the Aware State.
Aware State Buffer (Temperature)—Prevents the sensor from bouncing between Standard Operation and Aware State when the readings are very close to a threshold.

For example, if you set a Maximum Threshold (Above) to 90° and a Hysteresis of 1°, once the sensor takes an assessment of 90.0° and enters the Aware State, it will remain in the Aware State until the temperature drops to 89.0°. Similarly, at the Minimum Threshold (Below), the temperature must rise a degree above the threshold to return to Standard Operation.

Show Moisture Point—Displays the Altitude field for adjustable moisture weight.
Show Dew Point—Displays the dew point of the data.
Show Heat Index—Displays the human-perceived equivalent temperature based on temperature and relative humidity (RH).
Show Wet Bulb—Displays the temperature as if the thermometer is covered in a wet cloth.

Calibrate

Calibration Steps:

Place the sensor in an environment with stable temperature and humidity and wait for sensor readings to stabilize.
Enter the difference between the observed and actual humidity and/or temperature in the appropriate Offset text box and press Calibrate.

Sensor Scale Settings

To adjust the sensor scale settings:

Click the scale icon at the far right of the top menu in iMonnit.

With the Next Humidity Sensor, you can also display temperature values in either:

Fahrenheit
Celsius

Installation Steps

Step 1:

Follow the installation and setup steps in the Next Wi-Fi Sensor General Information Guide.

Mount the sensor in a location that will not block or impede airflow to the hole on the bottom of the sensor’s housing.

Step 2:

Configure the sensor’s settings and scale information in iMonnit for your specific application or use case.
