We don't just fix breakdowns. We predict them.

Smart sensors watch your motors, conveyors and crushers day and night. When a reading turns risky, the right person gets a WhatsApp message before the plant stops.

Industrial IoT installation

Sonny Predictive Tech is a South African IoT engineering company specializing in affordable predictive maintenance for businesses that cannot afford downtime.

Founded by Sonny — a qualified Electrical Technician and ESP32 IoT specialist working across South Africa — we saw a big problem: Farmers lose borehole pumps worth R25k without warning. Lodges lose cold rooms full of meat. Mines stop production because one motor burned.

Our solutions

GSM and IoT solutions for farms, lodges, factories, shops and homes. Most of them work without WiFi, on a normal SIM card.

Motor temperature + vibration monitor with SMS alert

Know before your motor burns. Save R20k to R150k in replacement cost.

Temperature sensors, a sensor board and cables laid out for motor monitoring

Problem we solve

  • Motor burns without warning: production stops
  • Borehole pump fails: no water for 3 days
  • Cold room compressor fails: meat rots, R30k loss
  • Gate motor overheats: gate stuck open, security risk
  • Aircon compressor vibration high: gas leak coming

Our solution: ESP32 GSM monitor

  • Temperature sensor (DS18B20 / IR): alert if above 80°C
  • Vibration sensor (SW-420 / MPU6050): alert if vibration is high
  • Current sensor (CT clamp): overload and dry-run alert
  • No WiFi needed: GSM 4G works on farm, mine and factory
  • Battery backup: still alerts during loadshedding
  • Logs every hour: temperature and vibration to your phone / cloud
  • Auto-stops the motor if temperature is critical, preventing fire

What the SMS says

ALERT Motor 2 Temp 95°C - Overheat! Check NOW
Vibration HIGH Motor 1 - Bearing failure coming
Motor 3 Not Running - Possible Trip / No Power

The boss sees who came late, on his phone. No WiFi needed!

Problem with the old book

  • Staff write 07:00 but come at 08:30: you lose money
