MPXA4115A picbasic code

I'll let Darrel help with the coding but, if you haven't used this sensor, you should be aware that decoupling its voltage supply line is critical (Figure 3 in the datasheet). Otherwise, it will be too noisy to make use of its output.

Thanks,
any suggestion for a practical good decoupling of the power supply based on your experience ?
Thanks

I used the 1.0µF and 0.01µF as well as the 470pF capacitor values shown in Figure 3 (Page 5) of the datasheet and the output was clean. Before adding them the output was wildly erratic. In my case, I used SMD ceramic caps.
