Two digital humidity and temperature sensors from Sensirion come in compact DFN packages with removable protective covers for added durability during handling and deployment. With package dimensions of just 1.5×1.5×0.5 mm, the SHT40-AD1P-R2 and SHT41-AD1P-R2 provide accurate measurements in space-constrained applications.
The SHT40-AD1P-R2 delivers ±1.8% RH accuracy (maximum ±3.5%) across 0 to 100% RH, with a response time (τ63%) of 4 s. Temperature accuracy is ±0.2°C, with a response time of 2 s. The SHT41-AD1P-R2 offers the same temperature performance and a tighter maximum RH accuracy of ±2.5%.
Both sensors integrate easily into a wide range of devices and systems via an I²C interface with a fixed 0x45 address. They require a 1.08-V to 3.6-V supply, draw 0.4 µA on average, and operate across a -40°C to +125°C temperature range.
The SHT40-AD1P-R2 and SHT41-AD1P-R2 digital humidity and temperature sensors are now available through Sensirion’s global distribution network.
