Cattle Monitoring
Sick animals do not display symptoms until they are very ill. A tracking solution was designed to detect health fluctuations and provide constant monitoring of livestock temperature, movement and other vital signs.
Gateway: SX1301
Transceiver for LoRa Modulation: SX127x
Each animal has biometric and environmental sensors connected to it
Data from all sensors is periodically sent to a gateway wirelessly
Gateway sends info to network server where data is analyzed
Reports are sent and ill animals are identified
Smart Street Lighting
Street lights in large cities are becoming more intelligent. Solutions are developed to better control light usage in order to minimize energy consumption without sacrificing public safety. Lights can be dimmed and controlled through the use of embedded sensors that can detect daylight intensity, cars and pedestrians passing by.
AC Linear Direct Drive of LEDs: TPS92411x (TI)
LED : XLamp family (Cree)
PIC24 MCU (Microchip)
Lora Gateway SX1301
Lora Transceivers SX127x
Sensors embedded in each street light have the ability to detect light functions
Gateway aggregates data from all street lights connected with sensors
Gateway sends information to the cloud where the data is analyzed by an application server
Application server controls lighting
Server sends maintenance alerts for burnt out bulbs and other malfunctions
Digital Radio
Digital radio offers much better quality sound than FM receivers, and unlike analog radio, is almost immune to noise and interference.
Antenna + RF Receiver(AM,FM) + Digital radio and processing system + Screen
LCD Screen: AIST0524 (Varitronix)
AM, FM Tuner: TDA7705 (ST)
Audio A/D Converter: AD1974 (Analog devices)
Digital radio and processing system-on- chip: SAF360X (NXP)
Sound is converted to digital code
Code is transmitted as digital signal
Digital radio receivers decode and filter all but the digital signal
Noise is discarded for static-free sound on the receiving end
Smart Power Meter
Smart meters have been used to measure the instantaneous electrical power per hour (KWh) and other more relevant details such as the power factor by using microcontroller circuit that sends the values to the base station through wireless network technology (Zigbee, Wi ,...). Smart meters monitor energy consumption more precisely, so better energy choices are made. Depending on the features set, the meters may also notify the utility of a power outage or allow the utility to remotely switch electricity service on or off.
MCU: MSP430F family (TI)
Zigbee Transceiver CC2520 (TI)
Current shunt Monitor NCS199xx (ON Semi)
LCD Screen FFSTN/ISTN (Varitronix)
Smart meter records energy consumption or power outage
Information is sent to base station through wireless network technology
Energy consumption is monitored at the utility
Utility is able to remotely switch electricity
Battery Power Management
Battery Management Systems are the brain behind battery packs. They manage the output, charging and discharging and provide notifications on the status of the battery pack. They also provide critical safeguards to protect the batteries from damage. Some applications include power bank charger, smart phone, tablet, energy storage system, chargers, uninterruptable power supplies (UPS), etc. Integrated Li-ION Battery Management: RAJ240xxx (Renesas)
Integrated Li-ION Battery Management: RAJ240xxx (Renesas)
Manages battery output
Provides notification on battery status
Protects battery from damage
Wireless Charger
Wireless Charging provides a convenient, safe, and reliable way to charge and power millions of electrical devices at home, in the workplace and in industry. By eliminating the use of physical connectors and cables, wireless charging provides better effciency, cost and safety advantages than the traditional charging cable.
Wireless Power Receiver IC: BQ510xxx (TI)
Wireless Power Transmitter IC: BQ500xxx (TI)
Energy is sent through an inductive coupling to an electrical device
Device uses that energy to change batteries or run itself
Motor Control System
Electric motors consume almost 50% of the world’s electricity. With the cost of energy rising steadily, industry is focused on replacing inefficient constant-speed motors with microprocessor-based, variable-speed engines. This new motor-control technology will reduce energy consumption by more than 30% compared to the older mechanisms and will increase motor functionality and performance.
