Two digital humidity and temperature sensors from Sensirion are available in compact DFN packages with detachable protecting covers for added sturdiness throughout dealing with and deployment. With bundle dimensions of simply 1.5×1.5×0.5 mm, the SHT40-AD1P-R2 and SHT41-AD1P-R2 present correct measurements in space-constrained functions.
The SHT40-AD1P-R2 delivers ±1.8% RH accuracy (most ±3.5%) throughout 0 to 100% RH, with a response time (τ63%) of 4 s. Temperature accuracy is ±0.2°C, with a response time of two s. The SHT41-AD1P-R2 presents the identical temperature efficiency and a tighter most RH accuracy of ±2.5%.
Each sensors combine simply into a variety of gadgets and techniques through an I²C interface with a hard and fast 0x45 handle. They require a 1.08-V to three.6-V provide, draw 0.4 µA on common, and function throughout a -40°C to +125°C temperature vary.
The SHT40-AD1P-R2 and SHT41-AD1P-R2 digital humidity and temperature sensors at the moment are obtainable by way of Sensirion’s world distribution community.
