TECHNOLOGIES
Powered by the ESP32-S3 Dual-Core AI Processor, sub-zero Sensirion SHT31 micro-heated humidity pods, DS18B20 stainless steel probes, and instant WhatsApp & Telegram push alerts.
Standard consumer sensors lock up in commercial freezers due to ice crystal formation. Microdrive Technologies builds hardware specifically engineered for sub-zero operation.
Standard consumer humidity sensors (like DHT11 or DHT22) fail completely in sub-zero commercial freezers because ice crystals form directly on their polymer grids, locking their readings permanently at 99.9% RH.
For commercial freezers (-20°C), Microdrive Technologies integrates industrial sensors like the Sensirion SHT31 / SHT40 or Bosch BME280, which feature internal micro-heaters to automatically clear ice condensation and deliver 100% accurate defrost diagnostics.
Ideal for commercial reach-in coolers and residential deep freezers requiring essential temperature monitoring and physical door contact.
Designed for walk-in commercial freezers, medical cold storage, and produce coolers requiring defrost diagnostics and light leak alarms.
Prevent inventory loss from compressor failures, thermal drift, or unsealed freezer doors.
Dual-Core Xtensa LX7 processor with vector extension AI acceleration running on-device machine learning models to detect compressor anomalies.
Integrates waterproof DS18B20 stainless-steel probes (-55°C to +125°C) alongside industrial micro-heated Sensirion SHT31 / SHT40 sub-zero humidity pods.
Direct integration with Telegram Bot API and CallMeBot WhatsApp gateway to dispatch mobile notifications within 200 milliseconds.
LDR ambient light detection tracks door-open duration and issues escalation alerts if a walk-in freezer door is left unsealed.
Local SQLite database engine records periodic temperature logs for compliance reporting and historical trend inspection.
Outbound TLS 1.3 encrypted tunnel pipeline delivering secure remote access on mobile browsers without router port forwarding.
