Description: HTU20D(F) is a digital humidity sensor with temperature output of MEAS. Setting new standards in terms of size and intelligence, it is embedded in a reflow solderable Dual Flat No leads (DFN) package with a small 3 x 3 x 0.9 mm foot print. This sensor provides calibrated, linearized signals in digital, I²C format. HTU20D(F) digital humidity sensors are dedicated humidity and temperature plug and play transducers for OEM applications where reliable and accurate measurements are needed. Direct interface with a micro-controller is made possible with the module for humidity and temperature digital outputs. These low power sensors are designed for high volume and cost sensitive applications with tight space constraints. Every sensor is individually calibrated and tested. Lot identification is printed on the sensor and an electronic identification code is stored on the chip – which can be read out by command. Low battery can be detected and a checksum improves communication reliability. The resolution of these digital humidity sensors can be changed by command (8/12bit up to 12/14bit for RH/T). With MEAS’ improvements and miniaturization of this sensor, the performance-to-price ratio has been improved – and eventually, any device should benefit from the cutting edge energy saving operation mode. Optional PTFE filter/membrane (F) protects HTU20D digital humidity sensors against dust and water immersion, as well as against contamination by particles. PTFE filter/membrane preserves a high response time. The white PTFE filter/membrane is directly stuck on the sensor housing.
Features:
Full interchangeability with no calibration required in standard conditions
Instantaneous desaturation after long periods in saturation phase
Compatible with automatized assembly processes, including Pb-free and reflow processes
Individual marking for compliance to stringent traceability requirements
典型應用: 家電，醫(yī)療，打印機，加濕器，多媒體：智能手機/平板電腦
行業(yè): 醫(yī)療, 工業(yè)控制, 消費電子和家用電器
產品描述: MEAS的新款數(shù)字式溫濕度復合傳感器HTU20D(F)樹立了新的濕度傳感器的尺寸和智能化典范：采用適合回流焊的DFN封裝，尺寸僅為3 x 3 x 0.9mm；提供經過校正的，線性的I²C數(shù)字輸出信號。HTU20D(F)作為一款即插即用的濕度和溫度復合傳感器，是需要可靠和精確測量的OEM應用的理想選擇。數(shù)字輸出的濕度和溫度信號可以直接與微控器接口。HTU20D(F)的功耗低，性價比高，尺寸小，所以適合價格敏感和安裝空間受限的OEM大批量應用。每個傳感器都經過校正和測試，批號不僅打印在外殼，而且存儲于傳感器芯片，以便通過指令讀取。用戶可以通過指令改變傳感器的分辨率（8/12bit至12/14bit）。此外，傳感器還可以檢測電量低，校驗和用于改善通訊可靠性�？蛇x的白色PTFE過濾器/膜直接粘貼在傳感器外殼上，使HTU20D不受灰塵和水汽影響，同時也可保護傳感器不受微粒污染。 MEAS通過對傳感器的不斷改善和微型化，HTU20D(F)的性價比不斷提升 - 同時，設備用戶還將受益于先進的節(jié)能工作模式。
特點:
完全可互換，無需重新校正
長期飽和后迅速恢復
適合無鉛回流焊等自動化裝配方式
單獨標識，符合嚴格的追溯要求
