Sensors track RH/temp in tight spaces
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.
