2.Description
HTU21D, the new humidity and temperature sensor 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 3mm foot print and 1mm
height it provides calibrated, linearized signals in digital, I²C format.
HTU21D 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 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 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.

For the Mosquito killer Led Bulb Light, is a 900 lumen bulb that doubles as an insect killer. The light features a blue UV LED which attracts insects into a Mosquito Killer grid.And the Mosquito Killer grid uses only 1W of electricity, while the light itself uses a meager 9W – and both can be used independently.They are used at home and outdoor. A brush is provided to clean off insects once the bulb switched-off.Compare to other traditional mosquito killer, this bulb has no chemicals, no sprays and hence no fumes to our life. • 2nd generation 2-in-1 LED LIGHT Bulb Plus LED Mosquito Killer Bulb • Wattage: 10W • Blue UV light • Lumen: 900-1000lm • Color Temperature (CCT): 6500K • Input Voltage: AC 90-130V & 220v-240V • With CE and ROHS Operation: Step1: Switch it on,both lighting +killing are on. Step2: Switch on again,light off,only killing on. Step3: Switch on again,killing off,only light on. Step4: Switch off, both off.
