SHT20-TR-1.5KS

Introduction: SHT20-TR-1.5KS is Sensirion’s SHT20 humidity and temperature sensor in Tape & Reel packaging, TR with 1.5K units per reel for high-volume SMT assembly. It provides a digital I2C output and is pre-calibrated.
What it is: A compact, low-power, digital RH and T sensor with a single I2C interface.
Key features:
- Measures relative humidity and temperature
- Operating range roughly −40 to +125°C; 0–100% RH
- Supply voltage around 1.8–3.6V
- Factory-calibrated, small footprint, low power
- I2C with simple commands; data readout includes optional CRC
Packaging and usage:
- TR means Tape & Reel packaging for automated placement; 1.5K parts per reel
- Ideal for consumer electronics, wearables, HVAC, environmental sensing, and IoT
- Typical integration: send a measurement command over I2C, read two data bytes (RH or T), convert per datasheet formulas
Note: For exact accuracies, timing, and conversion equations, consult the SHT20 datasheet.

SHT20-TR-1.5KS (Sensirion SHT20, tape‑and‑reel 1500 pcs) provides four electrical pins: VDD, GND, SDA, SCL (the small DFN package also has extra mechanical/no‑connect pads). Functions:
- VDD – supply voltage (typ. 3.3 V).
- GND – ground.
- SDA – I²C serial data (open‑drain; requires pull‑up).
- SCL – I²C serial clock (open‑drain; requires pull‑up).
The device uses a fixed I²C address (0x40).

- Manufacturer: Sensirion AG (Sensirion)
- What kind of company: A Swiss MEMS sensor company that designs and manufactures environmental sensors (humidity, temperature, gas sensors) for automotive, industrial, medical, and consumer electronics; privately held, headquartered in Staefa near Zurich.
