    7 Precautions
     
  7.1 The ceramic body of the sensor chip is mainly composed of lead zirconate titanate ceramics. Please ensure that the ceramic body complies with local environmental regulations when discarded.     
  7.2 The performance parameters mentioned in the specification refer to isolated components. Please fully estimate the influence of other factors when used in the whole circuit.     
  7.3 Sensor conductor, red is positive electrode, black is negative electrode. Pin: Long is positive, short is negative.     
    7.4 If you have any question about this specification, you can negotiate together.
