Wireless Sensor Applications using Dorji’f DRF5150S and DRf4432S Modules
Dorji Applied Technology from China builds different types of RF modules that can be easily incorporated in designing wireless data loggers, sensor network, telemetry and other wireless applications.
Some of their RF modules have an additional pre-programmed microcontroller that allows direct interface of selected analog and digital sensors to the module. This means you don’t need any external MCU or to write codes for these sensors. In this tutorial, Raj from Embedded Lab talks about their DRF5150S and DRF4432S RF modules which are very versatile and easy to use for wireless sensor applications. For illustrative purpose, Raj shows how to put them together to construct a simple wireless sensor application where data from a remote sensor are received and displayed on a PC, without using any external microcontrollers.

AMN12111 PIR Motion Sensor
PIR movement sensor module (Passive Infra Red) motion detection sensor AMN12111 is the smallest of objects the size of its shape. PIR motion sensor module (Passive Infra Red) AMN12111 fresneal come equipped with a lens. PIR motion sensor module (Passive Infra Red) AMN12111 has advantages can be directly connected to the microcontroller or other actuator driver.
PIR movement sensor module (Passive Infra Red) AMN12111 has a sensitivity that is very sensitive to changes in motion around it. PIR movement sensor module (Passive Infra Red) AMN12111 very suitable when applied to security systems. The price of the PIR movement sensor module (Passive Infra Red) AMN12111 not quite expensive. readily available in the market. For those of you who want to make a motion detection sensor. PIR movement sensor module (Passive Infra Red) AMN12111 is much easier and more practical than you have to make a series of Infra Red with the Tx and Rx.
