Temperature & Humidity Sensor module

Temperature & Humidity Sensor module is an intelligent system of sensors that can measure the amount of temperature & relative humidity in the air around the sensor.
This module has a digital data output is calibrated so that it can be used directly without additional calculations.
Example applications include modules for HVAC system (Heating, Ventilating, and Air conditioning), micro-climate control, weather stations, air humidity control,
as well as other applications that require temperature information and / or relative humidity of air.

Dimensions: 5 cm x 4.2 cm x 1.8 cm

Specifications:
- Range of measurement of temperature is -40 º C to +123.8 º C with a resolution of ± 0.1 º C.
- Accuracy of temperature measurement is ± 0.5 º C with the sensor response time from 5 to 30 seconds.
- Humidity measurement range is 0% to 100% RH (Relative Humidity) with a resolution of ± 0.1% RH.
- Accuracy of humidity measurement is ± 4.5% RH with the sensor response time 8 seconds.
- Having a digital interface option 2, ie UART TTL (38,400 bps) and I ² C (maximum 50 kHz clock).
- Line input / output voltage levels are compatible with TTL or CMOS.
- Maximum of 8 modules DT-SENSE Temperature & Humidity Sensor can be in-cascade within 1 point I ² C-bus (with 1 master).
- Requires power supply 4.8 V - 5.4 V DC.
- There are examples of applications using the DT-AVR Low Cost Nano System in C (CodeVisionAVR ©) to monitor the temperature and humidity.
