## Description

1

Review: Small and good magnetometer. The user manual should be enhanced by examples.
Review: EL sensor, versión modbus, funciona perfectamente, aunque al principio fue un poco difícil, puesto que la documentación inicial y el código de ejemplo no acababa de funcionar del todo bien. AL ponerme en contacto con el soporte técnico, el mismo día lo tuve resuelto, con una información más correcta y un código de ejemplo ejecutable perfectamente. Si no se conoce cóomo funciona el protocolo Modbus puede resultar dificultoso entender cómo operar con él.

Dem Produkt liegt ein Software bei für die man sonst noch viel bezahlt. Außerdem ist die Flugate genau genug auch Magnetische surveys durchzuführen.
