Low Cost IOT Small Pressure Sensor With SPI I2C 0.2-2.9V Output
Sleep Function
WNK has 13-year experience of research, development, production and
sales of sensors. With the concept of smart water management
system, smart fire control, sponge city, smart city, and internet
of things, WNK quickly seizes opportunities to develop low cost,
low power, small size, with temperature measurement function
ceramic capacitive pressure sensor.
After two years of research, development and repeatedly testings,
our ceramic capacitive sensors have
entered big quantity production stage. For different applications
and installation methods, we offer
OEM, ODM and customization services.
