Based on the rugged HUMIREL humidity sensor, GP3515 is a dedicated humidity and temperature plug and play transducer designed for OEM applications where a reliable and accurate measurement is required. Direct interface with a micro-controller is made possible with the moduleâ??s humidity linear voltage and direct NTC outputs. GP3515 is designed for high volume and demanding applications. Main features Tests under harsh chemical conditions demonstrate good operation in presence of salt atmosphere, SO 2 (0.5%), H 2 S (0.5%), O 3 , NOx, NO, CO, Softener, acids (H 2 SO 4 , HNO 3 , HCl), HMDS, Insecticide, Cigarette smoke . Product free from Lead, Cr (6+), Cd and Hg. Compliant with RoHS Reliability not affected by repeated condensations Full interchangeability. Better than +/-3%RH and +/-0.15°C Typical 1 to 3.6 Volt DC output for 0 to 100% RH at 5 V DC supply Humidity calibrated within +/- 3% RH @ 55% RH Temperature measurement through NTC 10 kΩ +/- 1% direct output Ratiometric to voltage supply within the specified range Resistance to chemical and physical stresses · GP3515 has circuit to protect against Electrostatic discharges upto 15 KV air discharge. · GP3515 is protected against reverse polarity · GP3515 is not light sensitive · Additional tests under harsh chemical conditions demonstrate good operation in presence of salt atmosphere, SO 2, O 3, NO, CO,CO2, Softener, Soap, acids. -
