Find cost-effective temperature/humidity monitor, gauges, or controllers for your application here.
Introduction
You don’t have to be a skilled Arduino master to read and display temperature or humidity for your environment. Several gadgets are available for this application. Specifically, temperature and/or humidity modules have ready probes or work stand-alone. There are also temperature controller modules that can automatically turn on or off an external appliance. Here, you can choose different kinds of temperature/humidity modules based on your needs.
What does it take to make a Temperature/Humidity Reading Device
Here are some of the elements needed to make a reliable temperature/humidity module.
Digital Display
The digital display acts as a visual representation of the current temperature or humidity, informing the user of these values. The display can be an LCD or a seven-segment module.
Mini MicRocontroller Unit
The mini microcontroller unit acts as the brain of the device. It serves different purposes, such as:
- As a converter of sensor data so that a program can act upon it.
- As a display driver of the LCD or seven-segment display module. The driver can be a separate chip.
- As an interpreter for the I/O interface of the module from which the user can interact.
Temperature/Humidity Sensor
The sensor is a transducer that picks up analog temperature or humidity data and sends it to the microcontroller. If the data has not been converted digitally, it can be converted here.
Control or Relay Unit
If you have a temperature/humidity controller, a control or relay unit is necessary to control your external appliance based on environmental conditions.
Different Kinds of Temperature/Humidity Modules
Temperature Gauges
Temperature gauges simply monitor the current temperature for you. They can have a long waterproof probe that measures temperature at the exact spot you want. Here are several places where you can use temperature gauges:
- Fish Aquariums
- Chilled products on store displays to keep them from spoiling.
- Freezers for meat and poultry.
- Scientific laboratory experiments

Temperature and Humidity Gauges
Sometimes, monitoring the temperature isn’t enough so you need to monitor humidity as well. Temperature and Humidity gauges both have temperature and humidity sensors that sense the environment. Below are example applications where you need to monitor both temperature and humidity:
- HVAC systems in offices or schools
- Server rooms to maintain the lifespan of IT equipment
- Food and Agriculture to monitor ideal growth conditions for plants
- Pharmaceutical setting to maintain proper levels of moisture and temperature needed to store medications.
- Clean room environment for semiconductor manufacturing
Temperature/Humidity Controllers
Sometimes, monitoring isn’t enough, and you’ll need to automatically control external equipment to maintain your desired temperature or humidity. This application requires temperature/humidity controllers. With this, you can hook up your heater or cooler equipment to the temperature/humidity sense module. Some examples of these applications are listed below:
- Turning ON or OFF a fan or cooler in a server room to protect IT equipment.
- Incubators for eggs or animals on farms.
- Control broilers or heaters in an HVAC system
- Greenhouse environment control
