precision humidity and temperature sensor

SHT45 is only 1.5 x 1.5 x 0.5 and is specified at ±1.0% relative humidity and ±0.1°C temperature accuracy.

AND, it draws under a μA 🙂

Here are the specs:

• 1% typical RH accuracy
• 0 – 100% RH range
• 4s humidity response time
• 0.1°C typical temperature accuracy
• -40 to 125°C range
• 2s temperature response time
• 1.08 – 3.6V operation
• 0.4μ average consumption
• I²C interface
• 1.5 x 1.5 x 0.5mm DFN packaging
  (0,7mm tall with filter membrane added)

Devices are available with factory-set I²C addresses of 0x44, 0x45 or 0x45

For less accuracy, there is the SHT40 or SHT41, and the SHT43 is ISO17025 certified.

Neat
