HTS221TR Typical application Circuitry

HTS221TR

The HTS221TR is a capacitive digital sensor for relative humidity and temperature by Microelectronics. This guide will provide a detailed process for establishing connections with this chip, paying attention to individual pins.As always, it's crucial to take appropriate ESD precautions when dealing with electronic components such as the HTS221TR.

1. Power Supply: Initiate by connecting the VDD pin to a stable 1.7-3.6V power source. The VDD pin provides power for the HTS221TR operations. Connect the system ground to the GND pin.

2. I2C Interface: The HTS221TR uses the I2C protocol for communication. Connect the SDA and SCL pins to the I2C bus of your microcontroller or another controlling device. It's necessary to include pull-up resistors on both SDA and SCL lines.

3. Address Selection: The HTS221TR allows for address selection via the SDO/SA0 pin. Connect this pin to VDD for high (1) and to GND for low (0). This provides flexibility in case you have multiple I2C devices on the same bus.

4. Interrupt Pins: The HTS221TR features two interrupt pins (INT1, INT2), which can be configured for various indications like data ready, humidity or temperature threshold levels. These can be connected to the interrupt input of your microcontroller or used to activate external circuitry.

5. Boot Pin: The Boot pin (BOOT) is used to ref lash the internal firmware if necessary. Under normal operation, this pin can be left unconnected.

6. Decoupling Capacitor: For power stability, it's recommended to place a decoupling capacitor (typically 100nF ceramic) as close as possible between the VDD and GND pins of the HTS221TR.

This guide serves as a basic overview for connecting the HTS221TR. Always refer to the specific HTS221TR data sheet for complete details and recommendations, including information on pin tolerances, maximum ratings, and precise operating conditions.
