The ZMOD4410AI1R is a TVOC (total volatile organic compound) and IAQ (indoor air quality) integrated sensor from Renesas, part of the ZMOD4410 family. It reports gas concentration measurements over an I²C digital interface, which means the sensor connects directly to a microcontroller's I²C bus without an external ADC — the conversion happens on-chip. Supply voltage is 1.7 V, and the switching current draw is 2.8 mA (0.0028 A). At 1.7 V the total power consumption is under 5 mW, which keeps the thermal contribution to the local air sample negligible — important when the sensor shares a board with a warm processor or power stage. Accuracy is specified at ±15 %. For a TVOC sensor this is the combined error across the full measurement range, including cross-sensitivity to humidity and temperature. A ±15 % tolerance means the reported ppb concentration is within 15 % of the true value — adequate for IAQ trend monitoring (demand-controlled ventilation, air purifier trigger thresholds) but not for compliance-grade gas analysis where ±5 % or better is required. The 65°C upper limit is below the 85°C typical for automotive-grade parts, so this sensor is suited for indoor building automation, HVAC duct mounting, and consumer appliances — not for engine-bay or industrial oven environments.
No second-source or pin-compatible alternative is listed on the record — the ZMOD4410 family is the sole source for this function.
