1. A detonator, comprising:
a substrate;
a first terminal mounted to the substrate and configured to be coupled to a first leg wire;
a second terminal mounted to the substrate and configured to be coupled to a second leg wire;
a controller mounted to the substrate, the controller coupled to the first and second terminals; and
a sensor coupled to the controller and configured to make multiple readings of a temperature, a pressure, or an acceleration;
wherein the sensor is inside an enclosure of the detonator;
wherein the sensor is powered by the controller; and
wherein the controller is configured to initiate environmental readings of the temperature, pressure, or acceleration in response to a demand from a remote master controller.
