Description
I2C-M8-TRH320: Precision temperature and humidity probe with a M8 waterproof IP67 connector, a dual dust filter and I2C protocol.
Based on the Sensirion SHT31 sensor, the I2C-M8-TRH320 is a specifically designed probe for temperature and humidity acquisition, in harsh and extreme humidity conditions. It is factory calibrated, linearized and temperature compensated. Thanks to its precision electronics, extremely small variations in temperature and humidity can be acquired. This makes the probe a convenient field interchangeable unit.
It is provided with a M8 waterproof IP67 standard connector for quick connection to our sensors that supports an external probe. The built-in particle filter provides protection against dust, soot and other contaminants. This product communicates using the standard I2C protocol.
It is also possible to use this probe with a wide variety of microcontrollers and single-board computers such as the Raspberry pi, Arduino and similar products, that supports the I2C communication protocol.

Do you have STEP/CAD files of your instruments?
You can find them on each instrument page under the Datasheets tab if available.
Are your sensors battery-powered?
No, they are not. They are powered via the USB plug; therefore, they must be plugged in to transmit data.

What are the advantages of choosing a calibratable instrument (-CAL option)?
The devices with the 3-point calibration mechanism have a longer lifetime as it is possible to compensate for the natural drift of the measurements. The cost/lifetime ratio is thus considerably reduced and, just as importantly, this choice is environmental friendly.
These devices can be easily calibrated and certified by external resources (including our ISO17025 certified partner laboratory) and allow you to synchronize your various devices between them.
What are the advantages of using your USB communicating devices over other technologies?
| 1. Connection security. | 6. Continuous power supply. |
| 2. Instant access to data. | 7. Low-power supply. |
| 3. Data confidentiality. | 8. Self-sufficiency. |
| 4. Data reliability. | 9. Technology persistence over time. |
| 5. Fast response time. | 10. Universal access. |
Can I use your measurement devices while maintaining my current software infrastructure?
Yes, you own your data. To integrate your data, you can either use our CLI (command line interface) for which we have plenty of code examples or for more advanced users, by choosing the VCP (Virtual COM Port) option when selecting your product.
How many devices can be simultaneously managed by your software tools?
Unlimited number of similar and different devices, provided your system supports the load.
What is your warranty policy?
Dracal Technologies guarantees the incomparable speed of use and the exceptional quality of its products, that they are made of new materials, assembled and tested in our factory in Canada, in processes that respect human rights and the environment. We guarantee the absolute absence of any form of programmed obsolescence, and that conversely, we deploy sustained efforts on both our electrical and mechanical designs to extend the life of our devices as long as possible so that the results of the efforts invested by our customers last over time but also, and just as importantly, to preserve our planet. We guarantee unlimited access to all updates of our free software tools. We offer a 2-year material warranty.
