Electrical Data

Power Input : 3.2V ~ 3.45V⁽³⁾⁽⁴⁾

Current Consumption : Normal mode : 12mA, Peak < 180mA , Sleep < 0.2mA

Note 1) IAQ application, accuracy is defined after minimum 3 times calibration for 3 weeks.

     2) +/- 2% is added for absolute measurements for uncertainty of calibration gas mixture unless the measurement is done with certified calibration mixtures.

3) DC Supply should be regulated , low noise power source for best accuracy.,

4) < 0.2mA of Low Power Consumption model

Product Derivatives and Relative Functions

S-300-3V has various output TTL-UART, I2C, ALARM, AVO (or PWM is selectable as option) and 2.54pitch 13pin side hole connector besides 2mm pitch 10 and 4pin 2 row header connectors. and

Periodic Automatic Calibration (ACDL) and Non-Periodic Manual Calibration (10’ MCDL) are executable by sending ‘Low Signal’ to pin-11 and pin-13.

There are 3 derivatives which has additional function on S-300-3V, S-300L-3V is Low Power model, consumes less than 0.2 mA in Sleep mode while as S-300G-3V is hardware-enforced one to be resistant to endure up to 99% humidity for customers whose application is Greenhouse and Stock Raising.

S-300A-3V has ACDL software and calibrate weekly after once in 2day from power-on, without ‘Low signal’ to J12-7 and J13-13 during operation, appropriate for Indoor Air-Quality Monitoring.
