i. Utilities (Water & Energy) Monitoring for
Property Management
For property managers & Developers, Our IoT solutions can be
used to efficiently manage and monitor your services e.g. automate metre
reading and billing with smart metres (Pre and post Paid), monitor water
tank levels and also manage and audit energy/electricity consumption.
With the postpaid smart metres, Property managers and tenants get
automated monthly bills eliminating the need to manually read metres and
prepare the water bills.
With the prepaid Smart metres consumers pay via Mobile Money (Mpesa)
to get water services.
6. ii. Logistics: Transportation & Warehouses
Monitor physical and environmental conditions in critical facilities in real
time e.g. Server rooms, cold rooms (warehouses) and vehicles that
transport sensitive goods & Products; mainly Horticulture &
Pharmaceutical goods (medicines, flowers, vegetables etc).

7. Definition and defining factors
● An embedded system is a combination of hardware and
software which is dedicated to a particular application
or product.
● It is embedded as a subsystem into a larger system
which may or may not be a computer system
● They are often electronic systems that use
microprocessors or microcontrollers but are not
considered as computers

11. Small scale embedded systems
● Use 8-bit - 16 bit MCUs
● Little hardware or software complexity
● Embedded software IDE specific to processor
● Software has to fit specific available memory
● Power consumption is limited
12. Medium scale ES
● Single or a few 16bit, 32bit microprocessor
● DSP or ARM used
● Both HW and SW complexities
13. Large scale ES
● Enormous hardware and software complexities
● Several processors used
● FPA, DSP, DSC, IPon VLSI chip,ASIC is used
● Hardware, Software or operating systems co design required.
● Some critical functions are designed in hardware for speed
purposes
● Development tools are costly
● Needs teamwork for development
14. SOC
● Many of the components of the embedded systems are
integrated on to one single chip. The concept is called
System on chip design
27. ● 32-bit ARM Cortex M3 clocked at 72MHz 3.3v logic
● 64 Kb of flash memory
● 20 Kb of SRAM
● 8MHz clock and 32kHz clock for RTC
● 2 USART interfaces
● 7-channel DMA
● 5VDC input voltage
● On-board SIM Module with antenna
● On-board WiFi Module
● USB Support
● SPI support
● SWD Interface
● 1 CAN interface
