The SHT series are digital temperature and humidity sensors developed by Sensirion. They’re widely used because of their accuracy, stability, and digital communication (I²C/Single-Wire/Analog, depending on model).

General Specifications:

• Humidity Range: 0 – 100 %RH
• Temperature Range: -40 °C to +125 °C (depending on model)
• Accuracy:
  Humidity: ±1.5% to ±3% RH (model dependent)
  Temperature: ±0.1 °C to ±0.3 °C
• Interface:
  Most common: I²C (2-wire digital communication)
  Some older models: proprietary 2-wire protocol
• Supply Voltage: 2.4V – 5.5V (depending on model)
• Low Power Consumption → suitable for battery-operated devices

Applications

• HVAC systems (air conditioning, ventilation)
• Weather stations
• Industrial process monitoring
• IoT devices (home automation, smart agriculture)
• Data loggers
