Overview
This is a multifunctional sensor that gives you temperature and relative humidity information at the same time.
It utilizes a TH02 sensor that can meet measurement needs of general purposes. It provides reliable readings when environment humidity condition inbetween 0-80% RH, and temperature condition inbetween 0-70°C, covering needs in most home and daily applications that don't contain extreme conditions.
Features:
- Wide operating voltage range:(3.3V ~ 5V)
- Low Power Consumption:350 µA during RH conversion
- 0 to 100% RH operating range
- Measuring Range: Humidity: 0% - 80% RH Temperature: 0 ~ 70 °C
- Accuracy: Humidity: ±4.5% RH
- Temperature: ±0.5°C
- I2C host interface
- Excellent long term stability

For well over one hundred years, people have been constructing machines that dispense fortunes to those who ask at the insertion of a coin and the push of a button. In modern days, this has taken the form of mobile apps that can be far more expansive, albeit with a lack of physical interaction. Seeing an opportunity to use an embedded speech recognition model in this kind of application, the Electronic Cats team built the aptly named Fortune Cat just in time for some Halloween fun. This small device, based on the Arduino Nano 33 BLE Sense, takes advantage of the onboard microphone to listen for words being spoken at the small cube. Performing the language processing is Cyberon’s Arduino Speech Recognition Engine, which was configured to listen for the wake phrase “Fortune Cat” and then later respond to “tell me my future” as its command phrase. After generating the model online, it was incorporated into the code via the DSpotter software development kit that lets the program check if either the wake or action phrase has been said and then act accordingly. In this case, asking Fortune Cat for your future will present one of 20 random phrases that get displayed on the OLED mounted to the top of the 3D-printed enclosure. To read more about how the Electronic Cats crew created and configured Fortune Cat, you can check out their write-up here on Hackster.io or watch their video below!
