Works with Arduino, Raspberry Pi, NodeMCUA new product of crowtail family, it’s a microwave sensor module which is applies the Doppler effect to detect moving objects using microwaves. This differs from the method used by a regular infrared (IR) sensor as microwave is sensitive to a variety of objects that are microwave-reflective, and its sensor readings are not affected by the ambient temperature. This type of sensor is widely used in industrial, transportation and civil applications such as measuring vehicle speed, liquid levels, automatic door motion detection, automatic washing, production line material detection and car reversing sensors etc. Model:CMS38743C The microwave detection method has the following advantages compared to other methods:
The Elevator Variable Frequency Drive is the 2nd generation dedicated elevator drive from Invertek Drives, designed to provide smooth, reliable carriage control in all elevator applications.The compact external dimensions simplify installation, whilst optional incremental/EnDat encoder feedback interfaces allow compatibility with a wide range of motors. Invertek's renowned motor control capability ensures maximum ride comfort under all conditions, with five independent S-ramps and dedicated motor holding brake control algorithm allowing fine tuning of the system. Elevator Variable Frequency Drive also incorporates Safe Torque Off* as standard, and a range of features including Rescue Mode.
OSH: SchematicsArduino GSM Shield 2 is open-source hardware! You can build your own board using the following files: EAGLE FILES IN .ZIP SCHEMATICS IN .PDF
SIM to use with this shieldThe GSM shield 2 is compatible with Data only and Voice and Data SIM. GPRS and SMS are supported by 2G Data only SIM, while voice calls, supported by the hardware, require a Voice and Data SIM, the same you may use in a GSM mobile phone. The Data transfer is based on GPRS technology and therefore it is not compatible with 3G or UMTS only network providers. GPRS is a 2G technology.
PowerIt is recommended that the board be powered with an external power supply that can provide between 700mA and 1000mA. Powering an Arduino and the GSM shield 2 from a USB connection is not recommended, as USB cannot provide the required current for when the modem is in heavy use.
On board indicatorsThe shield contains a number of status LEDs:
- On: shows the Shield gets power.
- Status: turns on to when the modem is powered and data is being transferred to/from the GSM/GPRS network.
- Net: blinks when the modem is communicating with the radio network.
On board interfacesThe shield comes with a on-board audio jack as well, and it can be used for both microphone and line inputs. It is also possible to make voice calls. You don’t need to add a speaker and microphone. There are two small buttons on the shield. The button labeled "Reset" is tied to the Arduino reset pin. When pressed, it will restart the sketch. The button labeled "Power" is connected to the modem and will power the modem on and off. For early versions of the shield, it was necessary to press the power button to turn on the modem. Newer versions of the board will turn the modem on automatically. If you have an early version of the shield, and it does not turn on automatically, you can solder a jumper to the CTRL/D7 pad on the reverse side of the board, and it will turn on when an attached Arduino receives power. Several of the modem pins are exposed on the underside of the board. These provide access to the modem for features like speaker output and microphone input. See the datasheet for complete information.
