What We Build
Hardware Capabilities & Custom Engineering
From single-unit proof-of-concept breadboards to deployed embedded sensor networks, Chemcool Electronics provides bespoke engineering solutions.
1. Custom Microcontroller Firmware
High-efficiency C/C++ development for Microchip ATmega, ATtiny, and Espressif ESP32/ESP8266 microcontrollers. We write clean, modular firmware designed for non-blocking execution, hardware timers, and deep sleep battery preservation.
- Bare-metal register and Arduino IDE C++ implementations
- Precise interrupt service routines (ISR) and PWM modulation
- I2C, SPI, and UART communication buses
2. IoT Sensor Nodes & Telemetry
Connect your physical environment to the cloud. We design wireless sensing nodes that monitor environmental conditions, power metrics, and atmospheric phenomena in real time.
- AS3935 Franklin lightning detectors with instant alerts
- Heltec ESP32 with built-in OLED and GPS telemetry
- WiFi / BLE low-power data broadcasting to remote dashboards
3. Solar & LiFePO4 Energy Telemetry
Maximize the longevity and insight into your South African solar setup. We decode Victron Bluetooth Low Energy advertisements and build smart chargers like our ESP32 "Solar Samba".
- Victron MPPT & EasySolar passive BLE packet capture
- LiFePO4 precision voltage balancing and charge cutoff
- Independent battery bank state-of-charge (SoC) logging
4. Custom Instrumentation & Retrofits
Replace outdated analog timers or revive vintage machinery. We engineer digital instrumentation for sports facilities, bench test equipment, and heavy industrial welders.
- PIR motion-activated workbench digital clocks
- Circuit training interval light controllers for fitness centres
- Arduino-controlled pulse modernizations for welding equipment
Our Prototyping Lifecycle
Requirements & Scope
We analyze electrical constraints, supply voltages, and data protocols to specify optimal components.
Schematic & Simulation
Circuit design and logic simulation ensuring pin allocations and pull-up resistances are balanced.
Breadboard & Code
Physical bench assembly in our Centurion lab, writing modular, commented C++ firmware.
Field Test & Delivery
Stress testing under fluctuating conditions followed by complete documentation delivery.
