Hi, I'm Lynn from Apollosense Ltd,As a professional supplier of sensors for 15 years,we specilized in Gas sensors,Pressure sensors,Liquid level sensors,Humidity sensors and so on. If you are interested with our products you can contact me any time. And the website of our company is www.apollounion.com ,you can learn about it there. Waiting for your early reply. DESCRIPTION Based on the rugged HS1101LF humidity sensor, HTF3226LF is a dedicated humidity and temperature transducer designed for OEM applications where a reliable and accurate measurement is needed. It features a miniature connector for easy, cost-effective mechanical mounting. Direct interface with a micro-controller is made possible with the module’s linear frequency output. FEATURES APPLICATIONS • The best combination of cost effectiveness and performance • Stable, linear proportional frequency output from 10% to 95%RH • Stable and reproducible characteristics with temperature • High reliability and long term stability Humidity Sensor Specific Features • Instantaneous de-saturation after long periods in saturation phase • Fast response time • High resistance to chemicals • Not affected by water immersion • Patented solid polymer structure Temperature Sensor Specific Features • High quality thermistor • Stable • High sensitivity

Humidity & Temperature sensor - HTU21D 1.Product Description: HTU21D, the new digital humidity sensor with temperature output of MEAS is about to set new standards in terms of size and intelligence: Embedded in a reflow solderable Dual Flat No leads (DFN) package of 3 x 3 mm foot print and 0.9 mm height it provides calibrated, linearized signals in digital, I²C format. HTU21D 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 humidity and temperature digital outputs. HTU21D digital humidity sensors are low power consumption 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. Furthermore, the resolution of HTU21D digital humidity sensor can be changed by command (8/12bit up to 12/14bit for RH/T), low battery can be detected and a checksum improves communication reliability. With made improvements and the miniaturization of the sensor the performance-to-price ratio has been improved – and eventually, any device should benefit from the cutting edge energy saving operation mode. 2.Main Application: • Automotive • Home Appliance • Medical • Printers • Humidifier • Multimedia: Smartphone, Tablet 3.Main 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. 4.

PCFS-IR2125A level sensor contact type, it is used for tube. The principle is infrared, output signal is analog. When there is no water, the sensor outputs low voltage value; When there is water, the sensor outputs a high voltage signal. The size can be customized. The photoelectric liquid level switch has high precision, low price, high reliability and wide application environment, it is less affected by strong acid, alkali and viscosity. Photoelectric level sensors can be used for higher liquid level accuracy requirements.
