MiraSense: The Seed Sensor That Never Misses

The Problem Hiding Inside Every Planter

Planting season moves fast. A farmer running a multi-row planter across hundreds of acres cannot afford to stop and check whether every seed is landing where it should. That job belongs to the seed sensor, a small device mounted on the seed tube that detects each seed as it passes and sends a count back to the display in the cab. When it works accurately, the farmer knows exactly what is happening across every row in real time. When it does not, seeds get missed, skips go undetected, and the problem only becomes visible months later at harvest when the yield map tells a story nobody wanted to read.

Why Dust and Size Have Always Caused Problems

Two variables have consistently undermined seed sensor accuracy for years. The first is dust. Planting is one of the dustiest operations on a farm. Soil particles, seed treatment residue, and fine debris circulate constantly through the seed tube environment. Many sensors cannot reliably distinguish between a seed passing through and a cloud of dust doing the same thing. The result is phantom counts, missed detections, and data that looks plausible but is not. The second variable is seed size. A farmer switching from corn to soybeans to sugarbeets to sunflowers is working across a significant range of seed diameters. A sensor calibrated for one performs differently on another, requiring adjustment, recalibration, and time that planting season does not offer.

What MiraSense Actually Does

The MiraSense seed tube sensor uses a powerful LED light source combined with an advanced dust rejection algorithm that actively distinguishes between seed and dust in real time. When a seed passes through the sensor, the LED reads its signature differently from particulate matter, and the algorithm filters the noise before it ever reaches the count. The result is accurate seed detection from seeds as small as 3.5mm all the way through large varieties, at rates of up to 70 seeds per second, without any calibration required. Switch crops, and the sensor keeps working. No adjustments. No downtime. No recalibration ritual between fields.

Designed to Fit What Is Already There

MiraSense installs as a direct drop-in replacement for existing seed sensors, mounting via cable ties to virtually any standard seed tube in use today. It connects through standard 3-pin Super seal or Weather Pack connectors, linking directly to the existing display in the cab without additional hardware. A farmer does not need to rebuild a planting setup around it. It fits into the one already running. That simplicity matters at the scale of a commercial farming operation where every hour of the planting window counts and every unnecessary complication costs.
