AM2305 Product Overview: 
 
AM2305 digital temperature and humidity sensor is a calibrated digital signal output of the temperature and
humidity combined sensor. It uses a dedicated digital modules capture technology and the temperature and
humidity sensor technology to ensure that products with high reliability and excellent long-term stability.
Sensor includes a capacitive humidity sensing element and a temperature measurement devices, and with a
high-performance 8-bit microcontroller connected. Therefore, the product has excellent quality, fast response,
anti-interference ability, high cost and other advantages. Each AM2305 sensors are calibrated in a precision
humidity calibration chamber. Calibration coefficients stored in the form of a program OTP memory, internal
sensor detection signal in the process to call these calibration coefficients. Single-wire serial interface, the system
integration becomes simpler and quicker. Ultra-small size, low power consumption, signal transmission distance up
to 20 meters, making all kinds of applications and even the most demanding applications the best choice is.
Products for the 4-pin single row pin package. Easy connection, special packages according to user needs and available.

Thin Film Pressure Sensor DF9-40 High Precise Force Sensing Resistor Resistance-type Flexible Pressure Sensor

This flexible pressure sensor is based on new nanometer pressure-sensitive materials supplemented by ultra-thin film substrate. Highly sensitive flexible nanometer materials can realize highly sensitive detection of pressure. It has pressure sensitive function as well as water-resistant function. When sensor detects outside pressure, the resistance of sensor will change. Pressure signal can be converted into a corresponding electrical signal output using simple circuit.

FSR406 Pressure Sensor , 100% New and Original Force Sensitive Resistor

This is a force sensitive resistor with a square, 1.75x1.5", sensing area. This FSR will vary its resistance depending on how much pressure is being applied to the sensing area. The harder the force, the lower the resistance. When no pressure is being applied to the FSR its resistance will be larger than 1MΩ. This FSR can sense applied force anywhere in the range of 100g-10kg.
