If you have a smart home or an automated greenhouse, it is a given that you will need to measure the ambient temperature and humidity. If you want to build your own climate control system, this Troyka temperature and humidity sensor is exactly what you’re looking for.

The sensor sends the data for temperature and humidity by one wire in the form of a digital signal. This allows you to transfer data easily over long distances.

In the heart of the module is the popular DHT11 sensor. It works via its own protocol. We packed all the features you need for easy operation using an Arduino in the finished library TroykaDHT11.


Connect the module via 3-pin jumper cable. The 3-pin jumper cable needed for the connection is included in the kit.

There are several different ways to wire this module:

Troyka Shield. The most straightforward method. Connect the module to a pin group on Troyka Shield with the 3-pin jumper cable and you’re ready to interface with it from your Arduino.

Troyka Slot Shield. The best choice for quick prototyping. Using slots on the shield, you can get rid of cables. The module will be held securely in place using both pin headers.

Breadboard. For advanced use. Troyka pin headers have 0.1” spacing which is compatible with any breadboard. Simply wire the module like you would do with any IC.
