Humidity Sensor Applications

Humidity sensors are used to achieve comfortable, safe, and efficient environments in a wide range of applications. They are typically used in HVAC systems to control the temperature of the room and to prevent respiratory issues from mold growth. Humidity sensors are also used in printers, ovens, greenhouses, food processing, and laboratory applications, just to …

Humidity Sensor Types

There are three primary humidity sensor types: capacitive, resistive, and thermal conductive sensors. The first two are designed to sense relative humidity (RH), and thermal conductivity sensors are used to detect absolute humidity (AH). A humidity sensor is one of the most important devices used in a wide range of applications to measure and monitor …

How Is Conductivity Measured?

Conductivity is measured using a conductivity meter and probe. A voltage is applied between two electrodes inside the conductivity probe when the probe is immersed inside a water sample. The resistance of the water causes a drop in the voltage, which is used to calculate the conductivity.  Conductivity measures the ability of a solution (usually …

Ion Exchange In Water Treatment

Ion exchange in water treatment involves removing undesirable ionic contaminants from the water by exchanging them with another ionic substance. The four methods of ion exchange are water softening, deionization, demineralization, and dealkalization.  It is essential to remove contaminants in water to make it safe.  When removing contaminants, the contaminant and the exchanged substance must …

What Is A Humidity Sensor?

A humidity sensor detects changes in temperature or electrical currents in the air, typically using a humidity probe connected to a receiving device. There are three types of humidity sensors: relative humidity (RH) sensors, absolute humidity (AH) sensors, and thermal humidity sensors.  If you have ever grown produce in a greenhouse, or your house is …

How To Decrease pH In Soil?

Soil pH is reduced by adding commercially available options like elemental sulfur, aluminum sulfate, and iron sulfate, or natural soil acidifiers like peat moss and compost. Is the pH of your soil too high? Did you know that soil that has a high pH creates toxic levels of certain nutrients, which are harmful to plants?  …

4 Types Of Temperature Sensors

There are four main temperature sensors used today in modern-day electronics: Negative temperature coefficient (NTC) thermistors, resistance temperature detectors (RTDs), thermocouples, and semiconductor-based integrated (IC) sensors.  Temperature sensors are essential to everyday life. They measure the amount of heat a system or object gives off, typically setting off an alarm when a temperature change exceeds …
