Long term exposure to conditions outside normal range, especially at high humidity, may temporarily offset the RH signal (e. Consequently, the I2C bus is blocked while VDD of the SHTC1 is set to 0 V. 2 Absolute Maximum Ratings Stress levels beyond those listed in Table 4 may cause permanent damage to the device. The master must keep the clock frequency within 0 to 400 kHz as specified in Table 6. The numbers above are values according to the I2C specification. 6 2 * Mold opening shows smooth transition to package surface. Warranty SENSIRION warrants solely to the original purchaser of this product for a period of 12 months (one year) from the date of delivery that this product shall be of the quality, material and workmanship defined in SENSIRION’s published specifications of the product. - Hysteresis - Repeatability2 Specified range4 extended5 time6 63% Typ. 4 Specified range refers to the range for which the humidity or temperature sensor specification is guaranteed. 2 The stated repeatability is 3 times the standard deviation (3σ) of multiple consecutive measurement values at constant conditions and is a measure for the noise on the physical sensor output. 5 ±3 ±3 ±3 ±3 ±3 ±3 ±3 ±3. 1 Power-Up and Communication Start Upon VDD reaching the power-up voltage level VPOR, the SHTC1 enters idle state after a duration of tPU. Power-up time tPU After hard reset, VDD ≥ VPOR - 182 239 Soft reset time tSR After soft reset. 4 Sensor Behavior during Measurement and Clock Stretching In general, the sensor does not respond to any I2C activity during measurement, i.
